Question

27. What is the Wavelength of an X-Ray that has a
Frequency of 3.5 x 10^17 Hz?

Answer 1

8.5*10-10

Step-by-step explanation:

Using Velocity= frequency×wavelength

3×10^8=3.5×10^17/W

• multiply both by 1/3.5×10^17

3×10^8×(1/3.5×10^17)=3.5×10^17/W × (1/3.5×10^17)

W=3×10^8/3.5×10^17

use calculator to divide, you'll get

W=8.5×10^-10
