Which statement about electromagnetic radiation is correct? a. As the wavelength decreases the energy decreases. b. The amplitude of a wave depends on the frequency. c. Radio waves have a smaller wavelength than visible light. d. As the energy decreases the frequency decreases. e. The wavelength and frequency are independent of each other.

Respuesta :

Answer:

Option (d) : As the energy decreases the frequency decreases

Explanation:

Option (d) is correct. The energy of any electromagnetic waves is given by :

[tex]E=h\times f[/tex]

or

[tex]E=\dfrac{hc}{\lambda}[/tex]

Where

h is the Planck's constant

f is the frequency of the wave

c is the speed of light

[tex]\lambda[/tex] is the wavelength of a wave

It is clear from equation (1) that the energy of any electromagnetic radiation is directly proportional to its frequency. As the energy decreases the frequency decreases. Hence, the correct option is (d).
