Question

Which of the following is the frequency range of Microwaves?

• A. 5$\times$${10}^{16}$ to 3$\times$${10}^{19}$
• B. 3$\times$${10}^7$ to 3$\times$${10}^{11}$
• C. 3.75$\times$${10}^{14}$ to 7.5$\times$${10}^{14}$
• D. 3$\times$${10}^{11}$ to 3.75$\times$${10}^{14}$

Answer 1

The correct option is B

3$\times$${10}^7$ to 3$\times$${10}^{11}$

Frequency of microwaves lies in the range of 3$\times$${10}^7$ to 3$\times$${10}^{11}$

Option (a) represents the frequency of X-Rays

Option (c) represents the frequency of visible rays

Option (d) represents the frequency of infrared rays
