Compton effect
The incoming photons' energy must be in the range of an X-ray frequency to generate the Compton effect. The electron does not lose enough energy that reduces the wavelength of scattered photons towards the visible spectrum. As a result, with visible lights, the Compton effect is missing.
Recoil Velocity
The amount of backward thrust or force experienced by a person when he/she shoots a gun in the forward direction is called recoil velocity. This phenomenon always follows the law of conservation of linear momentum.

Your Answer: AnswerQ3: Find the wave length of the electromagnetic radiation, which emitted, when a photon of energy (5eV) for electron transition from orbit to another? (Ans. 0.24µm).1. What is the wavelength of a radio photon from an AM radio station that broadcasts at 1470 kilohertz? Express your answer to three significant figures and include the appropriate units. 2. What is the energy of a radio photon from the same station? Express your answer to three significant figures and include the appropriate units. For question 1 I am not sure how to solve it because the frequency is in kilohertz and I don't know how to convert it into something that I can use. For the speed of light in this question, would it be best to use 3 x 10^8 m/s or 3 x 10^5 km/s? For question 2 I have the formula to use, I'm just uncertain of how to use it.
