13. What is the frequency of a wave that has a wavelength of 2.73 x 10-7m?​
ella [17]

Answer:

f = 1.09 × 10¹⁵ Hz

Explanation:

Given data:

Frequency of wave = ?

Wavelength of wave = 2.73 ×10⁻⁷ m

Solution:

Formula:

Speed of light = frequency × wavelength

speed of light = 3× 10⁸ m/s

by putting values,

3× 10⁸ m/s = f × 2.73 ×10⁻⁷ m

f = 3× 10⁸ m/s  / 2.73 ×10⁻⁷ m

f = 1.09 × 10¹⁵s⁻¹

s⁻¹ = Hz

f = 1.09 × 10¹⁵ Hz
