Question

indicate if the statement is true or false. radio waves are higher energy than infrared. choose ultra violet is higher frequency than microwaves choose visible light has longer wavelength than gamma rays choose microwaves have shorter wavelength than ultraviolet choose

Explanation:

Step1: Recall electromagnetic - spectrum properties

Energy of electromagnetic waves is directly proportional to frequency ($E = h
u$, where $h$ is Planck's constant). Frequency and wavelength are inversely - related ($c=\lambda
u$, where $c$ is the speed of light).

Step2: Analyze radio waves vs infrared

Radio waves have lower frequency than infrared. Since $E = h
u$, radio waves have lower energy than infrared. So the statement "Radio waves are higher energy than infrared" is false.

Step3: Analyze ultraviolet vs microwaves

Ultraviolet has a higher frequency than microwaves in the electromagnetic spectrum. So the statement "Ultra violet is higher frequency than microwaves" is true.

Step4: Analyze visible light vs gamma rays

Visible light has a longer wavelength than gamma rays. Gamma rays have very high frequencies and short wavelengths compared to visible light. So the statement "Visible light has longer wavelength than gamma rays" is true.

Step5: Analyze microwaves vs ultraviolet

Microwaves have longer wavelengths than ultraviolet. So the statement "Microwaves have shorter wavelength than ultraviolet" is false.

Answer:

1. False
2. True
3. True
4. False
