Question

The wavelength of X-ray is 1Å. calculate its frequency?​

Answer 1

frequency=c/wavelength

f=3*10^8/1*10^-10

f=3*10^18.... may be right answer....

hope it helps...!!!

Answer 2

Given - Wavelength

Find - Frequency

Solution - Wavelength and frequency are related to each other by the formula -

Speed of light = frequency*wavelength

As per the known fact, speed of light = 3*10⁸ m/sec

Keep the values in formula to find the frequency.

Frequency = $\frac{3 \times {10}^{8} }{ {10}^{ - 10} }$

Frequency = $3 \times {10}^{8 - ( - 10)}$

Frequency = $3 \times {10}^{8 + 10}$

Frequency = 3*10¹⁸ Hertz

Hence, the frequency of wavelength is 3*10¹⁸ Hertz.
