Question

The frequency (F) and length (L) of a wave are related by the following formula: F x L = 3.0 x 1010. Consider that the wavelength of violet light is 1.3 x 10−8. What is the frequency of violet light?

Answer 1

2.3 × 10^18

Explanation:

Your formula tells you ...

... F × (1.3 × 10^-8) = 3.0 × 10^10

Dividing by the coefficient of F, you have ...

... F = 3.0/1.3 × 10^(10-(-8))

... F ≈ 2.3 × 10^18
