In this diagram, which is the angle of incidence?
Angle A
Angle B
Angle C
Angle D
Which of the following IS NOT a behavior that light waves can undergo when they reach a boundary between two media?
stopping at the edge of the boundary
reflection off of the boundary
transmission into the boundary
refraction through the boundary
Reflection is to bouncing as refraction is to:
bending.
breaking.
dissipating.
halting.
This drawing illustrates the ________________________ of a light wave.
refraction
reflection
diffraction
dispersion
A concave mirror is shaped like the inner surface of a sphere. How do you think light rays will reflect off a concave mirror?
Reflected rays converge toward the center line of a concave mirror.
Reflected rays diverge away from the center line of a concave mirror.
Reflected rays reflect straight back at the angle that they came in.
Reflected rays are absorbed by a concave mirror.
The way that a surface reflects light depends on its texture. Rough surfaces such as cloth and wood tend to scatter light, reflecting it in many different directions. This type of reflection is called:
diffuse reflection.
specular reflection.
incident reflection.
distorted reflection.
A ray of light is incident towards a plane mirror at an angle of 30-degrees with the mirror surface. What will be the angle of reflection?
60o
30o
90o
45o

As fast as it would be in a vacuum
Slightly slower than the speed in a vacuum
Slightly faster than the speed in a vacuum
Light is unable to travel through air

00000002.3
2,300,000
According to the data, which media does light travel fastest through?
Air because it has the highest refractive index which means it is the most dense. The denser a medium is the faster the light wave will travel.
Air because it has the lowest refractive index which means it is the least dense. The less dense a medium, the faster the light wave will travel.
Diamond because it has the lowest refractive index which means it is the least dense, which means the wave will move the fastest.
Diamond because it has the highest refractive index which means it is the most dense. The denser a medium is the faster the light wave will travel.
The speed of light through water is 230,000,000 m/s per second. Refer to the data table to see the speed of a sound wave through water. What conclusion can I draw from the information?
Waves move at the same speed regardless of the type of wave
Mechanical waves (sound) move faster than Electromagnetic waves (liquid)
Electromagnetic waves (light) move faster than Mechanical waves (sound)
There is not enough data to answer the question
Why is the process of sunlight being broken into its constituent colors from water droplets forming a rainbow called (like a glass prism)?
scattering
dispersion
reflection
diffraction
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 dispersed by the prism, separating its colors through refraction
The light speeds up as it moves from air into the denser plastic material
Which of these is NOT an example of scattering of light?
Sky appears blue at midday
Sky appears reddish in the evening
Rainbow after rain
