Worksheet Overview

QUESTION 1 of 10

This is an Extension Physics Revision Paper for students doing Extension (Triple) Science and it covers physics topics. However, you also need to know material covered in Core and Additional Science.

Light is an example of ____________ radiation.

non-ionising

ionising

Light rays pass through through the cornea and the lens before reaching the __________ at the back of the eye.

In long sight distant objects are blurry.

true

false

Converging lenses focus light to make ________.

What is the unit of measurement for the power of a lens?

watt

metre

dioptre

What does the law of reflection state?

It states that the angle of incidence equals the angle of reflection.

It states that the angle of incidence is smaller than the angle of reflection.

If a light ray is travelling at an angle larger than the critical angle it will all be reflected when it enters a new medium where it travels faster. What is this called?

reflection

refraction

total internal reflection

Why do diamonds sparkle?

They have pieces of gold inside them.

They are good conductors of electricity.

They are cut so that their surfaces are at the best angle to increase total internal reflection.

Give one application of total internal reflection, apart from diamond cutting.

automatic carbon monoxide sensors

automatic rain sensors

automatic optical nerves

What type of waves are used to break up kidney stones?

The kinetic energy of an electron depends on its mass and its _____________.

power

weight

velocity

charge

What instruments are used to show a patient's organs working?

What is the medical device that uses electrical impulses, delivered by electrodes contracting the heart muscles, to regulate the beating of the heart?

Positrons have a negative charge.

true

false

What effect does the release of gamma rays have on the nucleus?

It becomes more radioactive.

It becomes more negative.

It becomes more stable.

What do isotopes of an element have?

They have the same number of protons but different number of neutrons.

They have the same number of neutrons but different number of protons.

They have the same number of neutrons but different number of electrons.

What does a proton consist of?

It consists of two 'up' quarks and a 'down' quark.

It consists of one 'up' quark and a 'down' quark.

It consists of one 'up' quark and two 'down' quarks.

Radiation can cause sudden changes in the DNA. What are they called?

What type of therapy can be used for the reduction in the size of tumours?

What is the name of the force that keeps an object moving in a circular motion?

  • Question 1

Light is an example of ____________ radiation.

CORRECT ANSWER
non-ionising
EDDIE SAYS
Light is an example of non-ionising radiation.
  • Question 2

Light rays pass through through the cornea and the lens before reaching the __________ at the back of the eye.

CORRECT ANSWER
retina
EDDIE SAYS
Light rays pass through through the cornea and the lens before reaching the retina at the back of the eye.
  • Question 3

In long sight distant objects are blurry.

CORRECT ANSWER
false
EDDIE SAYS
In long sight distant objects are clear, but near objects are not.
  • Question 4

Converging lenses focus light to make ________.

CORRECT ANSWER
images
EDDIE SAYS
Converging lenses focus light to make images.
  • Question 5

What is the unit of measurement for the power of a lens?

CORRECT ANSWER
dioptre
EDDIE SAYS
The power of a lens is measured in dioptres (D).
  • Question 6

What does the law of reflection state?

CORRECT ANSWER
It states that the angle of incidence equals the angle of reflection.
EDDIE SAYS
The law of reflection states that the angle of incidence is smaller than the angle of reflection.
  • Question 7

If a light ray is travelling at an angle larger than the critical angle it will all be reflected when it enters a new medium where it travels faster. What is this called?

CORRECT ANSWER
total internal reflection
EDDIE SAYS
When a light ray enters a new medium in which it travels faster at an angle larger than the critical angle, it is all reflected. This is called total internal reflection.
  • Question 8

Why do diamonds sparkle?

CORRECT ANSWER
They are cut so that their surfaces are at the best angle to increase total internal reflection.
EDDIE SAYS
Diamonds are cut so that their surfaces are at the best angle to increase total internal reflection, so they sparkle.
  • Question 9

Give one application of total internal reflection, apart from diamond cutting.

CORRECT ANSWER
automatic rain sensors
EDDIE SAYS
The phenomenon of total internal reflection is applied on the manufacture of automatic rain sensors for cars.
  • Question 10

What type of waves are used to break up kidney stones?

CORRECT ANSWER
ultrasound
EDDIE SAYS
High intensity ultrasound waves are used to break up kidney stones.
  • Question 11

The kinetic energy of an electron depends on its mass and its _____________.

CORRECT ANSWER
velocity
EDDIE SAYS
The kinetic energy of an electron depends on its mass and its velocity.
  • Question 12

What instruments are used to show a patient's organs working?

CORRECT ANSWER
fluoroscopes
EDDIE SAYS
Fluoroscopes are used to show a patient's organs working.
  • Question 13

What is the medical device that uses electrical impulses, delivered by electrodes contracting the heart muscles, to regulate the beating of the heart?

CORRECT ANSWER
a pacemaker
EDDIE SAYS
A pacemaker is the medical device that uses electrical impulses, delivered by electrodes contracting the heart muscles, to regulate the beating of the heart.
  • Question 14

Positrons have a negative charge.

CORRECT ANSWER
false
EDDIE SAYS
Positrons are similar to electrons but have a positive charge.
  • Question 15

What effect does the release of gamma rays have on the nucleus?

CORRECT ANSWER
It becomes more stable.
EDDIE SAYS
The release of gamma rays makes a nucleus more stable, because it loses energy.
  • Question 16

What do isotopes of an element have?

CORRECT ANSWER
They have the same number of protons but different number of neutrons.
EDDIE SAYS
Isotopes of an element have the same number of protons but different number of neutrons.
  • Question 17

What does a proton consist of?

CORRECT ANSWER
It consists of two 'up' quarks and a 'down' quark.
EDDIE SAYS
A proton consists of two 'up' quarks and a 'down' quark.
  • Question 18

Radiation can cause sudden changes in the DNA. What are they called?

CORRECT ANSWER
mutations
EDDIE SAYS
Radiation can cause sudden changes in the DNA called mutations.
  • Question 19

What type of therapy can be used for the reduction in the size of tumours?
