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 data:

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

every chemical equation adheres to the law of conservation of mass, which states that matter cannot be created or destroyed. therefore, there must be the same number of atoms of each element on each side of a chemical equation.
