Pulsed lasers are very similar to regular lasers, except they don't continuously emit laser light. Baby spice is looking at one on Ebay, and she finds a pulsed He-Ne laser that emits a cylindrical beam of light with a diameter of 0.750 cm. Each pulse lasts for 1.30 ns, and each burst contains an amount of energy equal to 3.00 J. Baby Spice has the following questions about this laser. (a) What is the length of each pulse of laser light? (b) What is the average energy per unit volume for each pulse? J/m³

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.
