Frank and Lisa are analyzing the chart, which shows the speed at which light travels through different media.Frank says that light travels through diamond with the greatest frequency. Lisa says that light travels through air with the greatest frequency.

Question illustration
A
Frank is correct because light travels through diamond at the slowest speed, and speed and frequency have an inverse relationship.
B
Lisa is correct because light travels through air at the fastest speed, and speed and frequency have a direct relationship.
C
Neither person is correct because light does not change frequency when it travels through different media.
D
Both people are correct because light has both an inverse and a direct relationship with frequency, depending on the media.

Which describes the relationship between the frequency, wavelength, and speed of a wave as the wave travels through different media?

A
As speed changes, wavelength changes and frequency remains constant.
B
As speed changes, frequency changes and wavelength remains constant.
C
As speed changes, wavelength and frequency change.
D
As speed changes, wavelength and frequency remain constant.

Wave Y and wave Z are two types of electromagnetic waves traveling through a vacuum. Suppose the frequency of wave Y is about three times greater than the frequency of wave Z.

A
It is the same for each wave because the amount of energy transferred is constant in all types of electromagnetic waves.
B
Wave Y transfers about one-third the amount of energy as wave Z because energy and frequency have an inverse relationship.
C
Wave Y transfers about three times the amount of energy as wave Z because energy and frequency have a direct relationship.
D
It is zero for each wave because when waves travel through a vacuum, they do not transfer energy.
