Question

Which of the following statements correctly compares the frequency and energy of infrared waves and ultraviolet waves?

A
Infrared waves have lower frequencies than ultraviolet waves. Since frequency and energy are directly proportional, infrared waves also have less energy than ultraviolet waves.

B
Infrared waves have lower frequencies than ultraviolet waves. Since frequency and energy are inversely proportional, infrared waves also have more energy than ultraviolet waves.

C
Infrared waves have higher frequencies than ultraviolet waves. Since frequency and energy are directly proportional, infrared waves also have more energy than ultraviolet waves.

D
Infrared waves have higher frequencies than ultraviolet waves. Since frequency and energy are inversely proportional, infrared waves also have less energy than ultraviolet waves.

Answer 1

Infrared waves have lower frequencies than ultraviolet waves. Since frequency and energy are directly proportional, infrared waves also have less energy than ultraviolet waves. (A)

Answer 2

The Correct Answer is A

Step-by-step explanation:

Infrared waves

• Infrared waves are the Infrared radiation is what we like to describe as a heat.
• We can not see the Infrared waves but we can sense the Infrared waves.
• Infrared waves are often used in restaurants to heat food.

Ultraviolet waves

• Ultraviolet waves have a number of uses in our day to day life.
• Ultraviolet waves are used in forgery detection.
• Ultraviolet waves can also cause tanned on our body's skin.
