Concept explainers

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.

An early LiDAR system was used to measure the distance to the moon. This system used a wavelength of 530 nm and a pulse-width of 25 nano-seconds. The transmit power was 10-15 Joules/pulse. (a) Assuming the average distance to the moon is 384,000 km, how long would it take for the laser pulse to make a round trip? Provide answer in seconds to two significant digits.The round-trip time is _____ s. (b) The LiDAR system was used to measure the distance to the moon. This measurement had an inherent uncertainty due to the range resolution of the laser. Based on the parameters given above, what was the range uncertainty (i.e. resolution) for this measurement?
