Question

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. Which best describes the accuracy of these statements? 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.

Answer 1

Neither person is correct because light does not change frequency when it travels through different media.

Answer 2

The correct answer is
c) Neither person is correct because light does not change frequency when it travels through different media

In fact, light changes both wavelength and speed when it travels through different media, but the frequency remains the same.
