Science Quiz - Light 02 (Questions)

Light in KS3 Science shows how we see, why shadows form, and how some animals have better night vision than humans thanks to their eye adaptations.

(quiz starts below)

Fascinating Fact:

Some animals, like cats and owls, can see better in low light than humans.

In KS3 Science, pupils explore how light travels, how shadows form, and how vision depends on light entering the eyes. Night vision in animals is an example of adaptation.

Key Terms

Pupil: The opening in the eye that controls how much light enters.
Shadow: A dark shape formed when light is blocked by an object.
Night Vision: The ability of some animals to see in low levels of light.

Frequently Asked Questions (Click to see answers)

How do animals see better in the dark?

Many animals see better in the dark because they have larger pupils and a reflective layer in their eyes, which increases the amount of light they can detect.

What makes a shadow form in KS3 Science?

A shadow forms when an object blocks light. The light cannot pass through, so a dark area is created behind the object.

Why do humans need light to see?

Humans need light because our eyes detect reflected light from objects. Without light, our eyes cannot pick up images, so we cannot see.

1.

In a solar eclipse, which of the following is true?

[ ]	The Earth is between the Sun and the Moon
[ ]	The Moon and the Earth are at right angles to each other
[x]	The Moon is between the Sun and the Earth
[ ]	The Sun is between the Moon and the Earth

In a lunar eclipse the Earth is between the Sun and the Moon

2.

When light travels from air to glass it does which of the following?

[ ]	It is all reflected
[x]	It slows down
[ ]	It speeds up
[ ]	It travels in the same direction

Some of it is reflected but most of it passes into the glass because glass is transparent

3.

Which of the following statements about light travelling from air to water is true?

[ ]	It is mainly deflected
[ ]	It is mainly dispersed
[ ]	It is mainly reflected
[x]	It is mainly refracted

A little of the light is reflected, but if the light enters the water at exactly a right angle, it will continue on in the same direction as it was travelling in air

4.

When light travels from air to glass at any angle other than ninety degrees, which of the following is true?

[ ]	It bends away from the normal
[x]	It bends towards the normal
[ ]	The direction will not change
[ ]	The speed is unchanged

The normal is a line drawn on a ray diagram to help to work out what will happen to a ray of light

5.

Light from the Sun is called:

[ ]	Blue light
[ ]	Red light
[x]	White light
[ ]	Yellow light

It contains all of the colours of the rainbow

6.

Colours are caused by light having different:

[ ]	Frequencies and speed
[x]	Frequencies and wavelengths
[ ]	Speeds
[ ]	Wavelengths and speed

Red light has the longest wavelength and lowest frequency

7.

Light can be split into colours of the spectrum using a prism. What is this process called?

[ ]	Deflection
[x]	Dispersion
[ ]	Reflection
[ ]	Refraction

Isaac Newton was the first person to investigate this

8.

The three primary light colours are:

[ ]	Blue, green and yellow

They are different from the primary colours of art

9.

Why does grass look green in daylight?

[ ]	It absorbs green and yellow light
[ ]	It absorbs green light
[ ]	It reflects green and yellow light
[x]	It reflects green light

In 1867 John Tyndall discovered why the sky is blue. Particles in the air scatter blue light more than red

10.

A red filter will only:

[ ]	Stop blue light
[ ]	Stop green and yellow light
[ ]	Stop red light
[x]	Transmit red light

It absorbs all of the other colours of light
