Question

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 .

Answer 1

Answer:

826.446 × 10∧8 Hz or s−1

Explanation:

Formula:

c= f×λ

c= speed of light

f = frequency

λ= wavelength

Given data:

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
