Your microwave oven emits radiation at 2.45 MHz (which can interfere with your WiFi). What is its wavelength?

wavelength = 1.22*10² m

Explanation:

Given dа ta:

Frequency of radiation = 2.45 MHz

Wavelength of radiations = ?

Solution:

Formula:

Speed of light = wavelength * frequency

Speed of light = 3 * 10⁸ m/s

Frequency of radiation = 2.45 MHz (1 MHz = 1000000 Hz)

= 2450000 Hz (1 s⁻¹ = 1 Hz)

Now we will put the values in formula.

3 * 10⁸ m/s = wavelength * 2450000 s⁻¹

wavelength = 3 * 10⁸ m/s / 2450000 s⁻¹

wavelength = 3 * 10⁸ m/s / 2.45*10⁶s⁻¹

wavelength = 1.22*10² m
