What is a rare occasion where light doesn't travel in a straight line?
When it undergoes refraction
Light not passing through an object of large mass such as the sun
When the light reflects off a surface
Interacting with any large object compared to the wavelength of the light
What is true about the speed of light in a vacuum?
It is always less than the speed of other materials
It is always greater than the speed of other materials
It changes from time to time
What is true about the frequency of a wave?
It changes as it travels from one medium to another
It determines the velocity
It is affected by the medium
It is fixed when the wave is created
What happens when a wave travels from a lower index of refraction to a higher index of refraction?
It bends towards the normal
It bends away from the normal
The angle of refraction is higher than the angle of reflection
The angle of refraction is lower than the angle of reflection
What happens if we keep increasing the angle of incidence?
It will randomly affect the angle of refraction
More light will leave the water
We will get to the critical angle when the angle of refraction is 90 degrees
We will have more external reflection
How can you see multiple colors when shining white light through a prism?
Because it is shiny
Because the index of refraction of materials is dependent on the wavelength
Because the light reacts with the prism
Because of light's intellectual powers

Crossing two crests
Crossing two troughs
Crossing a crest and a trough
