Question

A laser pointer emits light that has a wavelength of 5.32x 10–7 m. What is the frequency of the light?

Answer 1

Answer:

Frequency = 0.6 × 10¹⁵ s⁻¹

Explanation:

Given data:

Wavelength = 5.32 × 10⁻⁷ m

Frequency = ?

Solution:

Formula:

speed of light = wavelength × frequency

Frequency = speed of light / wavelength

Frequency =  3 × 10⁸ m/s /  5.32 × 10⁻⁷ m

Frequency = 0.6 × 10¹⁵ s⁻¹
