Q

What is a real image?

A

An image that can be projected onto a screen

19
Q

What is a virtual image?

Green
Blue
Indigo
Violet

21
Q

Which colour has the longest wavelength?

A

Red

22
Q

Which colour has the shortest wavelength?

A

Violet

23
Q

Which colour has the highest frequency?

A

Violet

24
Q

Which colour has the lowest frequency?

A

Red

25
Q

When a particle absorbs radiation, what increases?

A

It’s internal energy

26
Q

How can we see blue?

A

A spectrum of white light will hit the object, all the colours of the visible light spectrum will be absorbed, apart from blue which is reflected into our eyes

27
Q

If an object absorbs all light, what colour will it appear?

A

Black

28
Q

How would you filter the colour of a ray of white light?

A

You would use colour filters

29
Q

What happens when the angle of incidence is smaller than the critical angle?

A

Refraction

30
Q

What happens when the angles of incidence is larger than the critical angle?

A

Total internal reflection

31
Q

What is the critical angle?

A

The angle of incidence where the angle of reflection will be 90°

32
Q

What happens when a light ray hits a concave lens at an angle?

A

It diverges
