Question

A wavelength of 4.73 x 10-7 m, and a frequency of

Answer 1

Frequency =0.634×10¹⁵ s⁻¹

Step-by-step explanation:

Given data:

Wavelength = 4.73×10⁻⁷ m

Frequency = ?

Solution:

Formula:

speed of light = wavelength× frequency

speed of light = 3×10⁸ m/s

Now we will put the values in formula.

3×10⁸ m/s = 4.73×10⁻⁷ m × frequency

Frequency = 3×10⁸ m/s /4.73×10⁻⁷ m

Frequency =0.634×10¹⁵ s⁻¹

s⁻¹ = Hz

Frequency =0.634×10¹⁵ Hz
