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.
