CP Čerenkov Radiation . The Russian physicist P A. Čerenkov discovered that a charged particle traveling in a solid with a speed exceeding the speed of light in that material radiates electromagnetic radiation. (This is analogous to the sonic boom produced by an aircraft moving faster than the speed of sound in air; see Section 16.9. Čerenkov shared the 1958 Nobel Prize for this discovery.) What is the minimum kinetic energy (in electron volts) that an electron must have while traveling inside a slab of crown glass ( n = 1.52) in order to create this Čerenkov radiation?w

Study of body parts and their functions. In this combined field of study, anatomy refers to studying the body structure of organisms, whereas physiology refers to their function.
One molecule of ATP provides 0.3 eV when used by the cell. Photosynthesis in a typical plant uses 8 photons at the nominal wavelength of 525 nm to produce 1 ATP. What percentage of the light energy is converted into chemical energy in the form of ATP? Give your answer to 2 significant digits.
*0.016 is incorrect
1. An incoming light beam has frequency 9.7 x 1014 Hz. (Use h=6.626 x 10-34 J.s)
a.) How much energy in Joules does it have?
b.) If the photons of this light beam are absorbed by a free electron, how much kinetic energy and speed will the free electron have?
