Microwaves, such as those used for radar and to heat food in a microwave oven, have wavelengths greater than about 3 mm. What is the frequency of radiation of wavelength 3.63 mm? Answer in units of s-1.

826.446 * 10∧8 Hz or s-1

Explanation:

Formula:

c = f*λ

c = speed of light

f = frequency

λ = wavelength

Given dа ta:

wavelength = 3.63 mm

speed of light = 3 * 10∧8 m/s

frequency = ?

Solution:

First of all we sill convert the 3.63 mm into meter,

3.63/1000 = 0.00363 m

Now we will put the values in formula:

c = f*λ

f = c/λ

f = 3 * 10∧8 m/s / 0.00363 m

f = 826.446 * 10∧8 Hz or s-1
