Based on the image, as light passes from medium 1 to medium 2
light speeds up and bends towards the normal
light speeds up and bends away from the normal
light slows down and bends towards the normal
light slows down and bends away from the normal
When light passes at an angle to the normal from one medium into another in which its speed is higher
it is bent toward the normal.
it always lies along the normal.
it is unaffected.
it is bent away from the normal.
If all other variables are held constant, what happens to the angle of refraction if the angle of incidence increases?
the angle of refraction stays the same
the angle of refraction decreases
the angle of refraction increases
cannot be determined from the information provided
Swimming pools and the ocean look shallower than they really are due to:
reflection
dispersion
refraction
total internal reflection
What is this image showing?
Reflection
Refraction
The law of reflection
Concave Mirror
Why is the spectrum of light separated into its components of color when white light is directed to a prism?
Because light reflects off the prism's surface
The incident white light refracts and separates into its constituent colors
The white light is absorbed by the prism, separating its colors
The light speeds up as it moves from air into the denser plastic material
Glass has a _____________ index of refraction than air.
Equal
Greater
Less
Impossible to say
Why does the lower part of the child appear so much different in size from the upper part?
The light rays that travel through water and then into air are refracted.
The light rays that travel through water and then into air are enlarged.
The light rays that travel through air and then into water are reflected.
The light rays that travel through air and then into water are reduced.
Why does the straw appear to be bent?
light is reflected
light is absorbed
light is turned
light is refracted
According to Willebord Snell, light passing from air to glass will cause the light to
maintain its original speed
accelerate while it is in glass
increase its speed
reduce its speed
This shows the phenomenon known as....
reflection
refraction
mirrors
focal point
When a red light ray travels from air into a glass block, its
velocity increases and its wavelength decreases
velocity decreases and its frequency stays the same
velocity decreases and its frequency increases
velocity remains the same and its wavelength decreases
What is the index of refraction a measure of?
The speed of light in a vacuum compared to its speed in a medium
The angle at which light is reflected from a surface
The wavelength of light in a medium
The frequency of light in a vacuum
If a light ray passes from water (n=1.33) into diamond (n=2.42), what happens to its speed?
It increases
It decreases
It remains the same
It becomes zero
Which of the following equations correctly represents Snell's Law?
n1sinθ1=n2sinθ2
n1+n2=sinθ1+sinθ2
n1cosθ1=n2cosθ2
n1tanθ1=n2tanθ2
