Question

Infrared radiation has a longer wavelength, ____ frequency, and ____ energy than visible light.

Answer 1

Infrared radiation has a longer wavelength, HIGHER frequency and LOWER energy than visible light.
Hope this helps!!!!!!!

Answer 2

Answer: The correct answer is lower, lower.

Explanation:

The relation between energy and wavelength of light is given by Planck's equation, which is:

$E=\frac{hc}{\lambda}$       .....(1)

where,

E = energy of the light

h = Planck's constant

c = speed of light

$\lambda$ = wavelength of light

We also know that:

$\nu=\frac{c}{\lambda}$     ......(2)

where,

$\nu$ = frequency of light

From equation 1 and 2, we get that wavelength is inversely proportional to energy as well as frequency of the light. So, if the wavelength of light is high, that means energy and frequency will be low.

Hence, the correct answer is lower, lower.
