Question

A. wavelength of microwave is greater than that of ultraviolet rays.
B. The wavelength of infrared rays is lesser than that of ultraviolet rays.
C. wavelength of microwave is lesser than that of ultraviolet rays
D. Gamma rays have the shortest wavelength in the electromagnetic spectrum.
Choose the correct option from the given options.

• A. A and B are correct
• B. B and C are correct
• C. C and D are correct
• D. A and D are correct

Answer 1

The correct option is D

A and D are correct

The explanation for correct options:

Option A:

1. Since the frequency of the microwave is lower than that of the ultraviolet rays, the wavelength of the microwaves is longer.
2. Hence, it is the correct option.

Option D:

1. Gamma rays have the highest frequency in the electromagnetic spectrum.
2. As a result, it has the shortest wavelength.
3. Hence, it is the correct option.

Explanation for incorrect options:

Option B:

1. Infrared rays have a longer wavelength than ultraviolet rays.
2. Hence, it is the incorrect option.

Option C:

1. In addition, microwaves have a longer wavelength than UV radiation.
2. Hence, it is also the incorrect option.

Hence, A and D are the correct statements.

Therefore, option (D) is the correct answer.
