Question

Find the wavelength of microwaves coming from a
source of 24000 MHz.?​

Answer 1

Answer:

0.125m

Explanation:

velocity(meter per sec) =frequencyHz) × wavelength(m)

3×10^8=2400×10^6 ×wavelength

Wavelength=0.125m

Hence, the frequency of microwaves used in microwave oven is 2400MHz. The wavelength of these waves will be 0.125m

Answer 2

The wavelength of microwave is 1.25*10-¹⁰ metres.

Given - Frequency

Find - Wavelength

Solution - The wavelength can be calculated by the formula - speed of light/frequency

Speed of light = 3*10⁸ m/s

1 MHz = 10⁶ Hz

Frequency = 24000*10⁶ Hz

Wavelength = $\frac{3 \times {10}^{8} }{24000 \times {10}^{6} }$

Wavelength = $\frac{3 \times {10}^{8} }{24 \times {10}^{9} }$

Performing division

Wavelength = 0.0125

Hence, the frequency is microwave is 1.25*10-¹⁰ metres.
