Question

Match the EM wave type to the correct description. A. Gamma ray B. X-ray C. Ultraviolet D. Visible light E. Infrared F. Microwave G. Radio/TV waves - Part of the spectrum the human eye can see- Highest energy EM wave-High frequency wave dangerous to human skin-Often used for medical imaging-Medium frequency wave-Low energy wave sometimes used to heat food-Low energy wave sometimes used to heat food-Longest wavelength EM wave

Answer 1

This is the order of the spectrum from highest frequency to lowest frequency:
Gamma Ray (Highest energy em wave)
X Ray (Used in medical imaging)
Ultra violet (dangerous to human skin)
visible light (human eye can see)
Infrared (medium frequency)
Microwave (used to heat food)
Radio (longest wavelength)

Answer 2

Answer:

A. Gamma ray

- Highest energy EM wave

B. X-ray

-Often used for medical imaging

C. Ultraviolet

-High frequency wave dangerous to human skin

D. Visible light

- Part of the spectrum the human eye can see

E. Infrared

-Medium frequency wave

F. Microwave

-Low energy wave sometimes used to heat food-Low energy wave sometimes used to heat food

G. Radio/TV waves

-Longest wavelength EM wave

Explanation:

As we arrange the electromagnetic waves in increasing order of energy and frequency from lowest to highest then it is given as

1. Radio Waves

2. Microwaves

3. Infrared waves

4. Visible Light

5. Ultraviolet waves

6. X - Rays

7. Radio waves

So as per the energy range we can say most energetic waves are gamma rays and least energy waves are Radio waves and their uses are as mentioned above
