Question

The frequency (F) and length (L) of a wave are related by the following formula: F x L = 3.0 x 10^10. Consider that the wavelength of violet light is 1.3 x 10^−8. What is the frequency of violet light?

A) 1.7 x 102
B) 2.3 x 102
C) 2.3 x 1018
D) 4.3 x 107

Answer 1

B: 2.3 x 10^18

expination:

Substitute values into the formula.

F x L = 3.0 x 10*10

F x 1.3 x 10^−8 = 3.0 x 10^10

F = 3.0 x 10^10 1.3 x 10^−8 F = 2.3 x 10^18

Answer 2

The correct answer: 2.3 x 10^18
