3How can we see certain colours in objects?
When [blank_start]white light[blank_end] hits a surface, some colours will [blank_start]reflect[blank_end] from the surface and others will [blank_start]be absorb.[blank_end] We can only see [blank_start]the reflected[blank_end] colours.- Areflect
- Bbe absorb.
- Cthe reflected
- Dwhite light
4What is a crest?
- Ahighest part of a wave
- Blowest part of a wave
- Cthe distance between 2 crest or 2 trough
- Ddistance between the origin and crest (or trough)
5What is an amplitude
- Ahighest part of a wave
- Blowest part of a wave
- Cthe distance between 2 crest or 2 trough
- Ddistance between the origin and crest (or trough)
6What is a trough?
- Ahighest part of or a wave
- BLowest part of a wave
- Cthe distance between 2 crest or 2 trough
- Ddistance between the origin and crest (or trough)
7What is a wavelength?
- Ahighest part of a wave
- Blowest part of a wave
- Cthe distance between 2 crest or 2 trough
- Ddistance between the origin and crest (or trough)
8The [blank_start]shorter[blank_end] the wavelength, the greater the frequency
- Ashorter
9the longer the wavelength and lower the frequency results in [blank_start]lower[blank_end] energy
- Alower
10The [blank_start]shorter[blank_end] wavelength and higher the frequency corresponds with greater energy
- Ashorter
11What are the some of the eye parts?

12Which one of these choice are the definition of diffuse reflection?
- AIt's when light reflects from a smooth surface at a define angle.
- BIt's when light reflects on rough surfaces that tend to reflect light in all direction.
13Which one of these choice are the definition of specular reflection?
- AIt's when light reflects from a smooth surface at a define angle.
- BIt's when light reflects on rough surfaces that tend to reflect light in all direction.
14True or false,
concave mirrors reflects inwards instead of outwards?- ARichtig
- BFalsch
15True or false,
Convex mirrors makes the object larger than it appears- ARichtig
- BFalsch
16Why is light refracted in water or glass?
When light travels from air to water, it [blank_start]slows down[blank_end] causing it to change direction slightly. It's called [blank_start]refraction[blank_end] when light enters a more dense substance, it "bends" more towards the normal line.- Arefraction
- Bslows down
17What is a focal point?
- AWhen light rays converge together.
- BIt's the point where the light reaches the retina
- CWhen light rays starts to spread form each other
- DIt's a part of the eye close to the retina
18What aspect of the human eye is similar to a camera lens?
