Question

An electromagnetic wave that has a lower frequency than infrared radiation will have ____ than the infrared radiation. longer wavelength and higher energy

Answer 1

Longer wavelength and lower energy

Hope this helps : )

Answer 2

Longer wavelength

Step-by-step explanation:

The spectrum in which the wavelength or frequency are arranged in increasing or decreasing order is called electromagnetic spectrum. The frequency of gamma rays is maximum while the frequency of radio wave is least.

We know that the frequency and wavelength are inversely proportional to each other.

So, an electromagnetic wave that has a lower frequency than infrared radiation will have longer wavelength. Also the energy of wave is given by :

E = hυ, where υ is frequency of the wave

Hence, the correct option is (a) " longer wavelength ".
