Answer:
Explanation:
Given that,
The wavelength of x ray,
We need to find the energy if a photon on the x-rays. The formula for the energy of the photon is given by :
So, the energy of a photon of the X-rays is . Hence, this is the required solution.
Answer: B
Explanation: the teacher just told us the answer
Hello, it is the wave period.
One wavelength is considered to be two successive crests, which makes the time taken by a wave to travel this distance the wave period.
Hope it helps!
