Question

Which of the following types of electromagnetic radiation has the shortest frequency

Infrared Waves

Microwaves

Ultraviolet Waves

X-rays

Answer 1

The answer is the last choice, X-rays.

Answer 2

Microwaves has the shortest frequency.

Step-by-step explanation:

In an electromagnetic spectrum, the different waves are arranged in an increasing or decreasing order of wavelength or frequency. Frequency of a wave is defined as the number of oscillations or vibrations produced. We have to write the name of wave having shortest frequency.

Frequency of infrared wave,
`f_1=3* 10^(12)\ Hz-4,3* 10^(14)\ Hz`

Frequency of microwaves wave,
`f_2=3* 10^(9)\ Hz-3* 10^(12)\ Hz`

Frequency of ultraviolet waves,
`f_3=7,5* 10^(14)\ Hz-3* 10^(16)\ Hz`

Frequency of x-rays,
`f_1=3* 10^(16)\ Hz-3* 10^(17)\ Hz`

So, from the above data it is clear that the microwaves has the shortest frequency.

Hence, the correct option is (b) " microwaves ".
