A beam of yellow monochromatic light passes from quartz (n = 1544) into
water (n = 1333). In the water, the beam makes an angle of 35.0° with the
normal. When the beam is traveling in the quartz, what angle does it for with
the normal? (A) 25.1 (B).29.8 (C)38.9 (D) 20.6

Which describe reflection? check all that apply. light bounces off a boundary.

The mass of a muon is 207 times the electron mass; the average lifetime of muons at rest is 2.21 μs. in a certain experiment, muons moving through a laboratory are measured to have an average lifetime of 7.04 μs. for the moving muons, what are (a) β (b) k, and (c) p? the rest energy of the electron is 0.511 mev.

The earth remains in orbit around the sun due to the force of gravity. how does the force of gravity exerted by the sun on the earth compare to the force of gravity exerted by the earth on the sun?
