They can change direction by reflection
The _______________ determines the color of visible light.
wavelength (and frequency)
speed
amplitude
particles of the medium
All electromagnetic waves are...
transverse waves and have the same frequency
transverse waves and have the same speed
mechanical waves and have the same wavelength
longitudinal waves and have the same energy
Which of the following occurs as light travels farther from its source?
Far from the source, photons come together in a small area.
The intensity of light increases as photons move away from the source.
The source gives off less light as photons move away from it.
Far from the source, photons spread over a larger area.
Which portion of the electromagnetic spectrum is used to identify fluorescent minerals?
infrared
x rays
ultraviolet
gamma rays
When red light is compared with violet light
both travel at the same speed
red light travels faster than violet light
both have the same wavelength
both have the same frequency
Which shows light as it passes through a polarizing filter/?
Which shows light as it travels through air and then glass?
Light waves bouncing off a surface is known as?
Transmission
Refraction
Reflection
Absorption
This is the term that describes when light passes through matter.
Transmission
Transparent
Translucent
Opaque
This is when light changes direction slightly when it passes from one material to another.
Transmission
Reflection
Refraction
Absorption
This describes when the atoms of matter absorb light, and converts the light into thermal energy.
Transmission
Reflection
Refraction
Absorption

An ____________ is the inner, darker part of a shadow.
penumbra
umbra

heat-trapping
opaque
soft
The production of light with a specific pattern of oscillation.
reflection
polarization
refraction
diffraction
The Law of reflection states that...
the angle of reflection from a mirror equals the angle of incidence.
waves incident on a mirror are partially reflected.
all waves incident on a mirror are reflected.
the angle a ray is reflected from a mirror is random.
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
these are examples of phenomenon of scattering of light except
Sky appears blue at midday
Sky appears reddish in the evening
Rainbow after rain
Why does scattering of light occur?
Light rays are reflected by atmospheric molecules and scatter in all directions
Light rays are blocked and refracted to all directions by the clouds or particles in the air
Light rays are transmitted and refracted in all directions by the clouds or particles in the air
