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

Explanation:

The speed of the wave depends on the medium through which it is travelling. The speed of the light is more in the rarer medium than the denser medium.

Frank says that light travels through diamond with the greatest frequency. Lisa says that light travels through air with the greatest frequency. Both are wrong as the frequency remains constant when the light is travelling from one medium to another. The speed of light is lowest in diamond.

Therefore, the correct option is (c).
