Q. 4.48
Question
Identify the form of electromagnetic radiation in each pair that has the greater energy:
a. Radio waves or violet light.
b. Infrared light or ultraviolet light.
Step-by-Step Solution
Verified(a)Violet light has greater energy than radio waves.
(b)Ultraviolet light has greater energy than infrared light.
We have been given that,
Radio waves, violet light
We need to find which of the two has greater energy.
Violet light has greater energy than radio waves.
Since violet light has less wavelength than that of radio waves ,therefore energy is greater.
We have been given that,
Ultraviolet light, infrared light.
We need to find which of the two has greater energy.
Ultraviolet light has greater energy than infrared light.
Since ultraviolet light has less wavelength than that of infrared light ,therefore energy is greater.
