Electrons are ejected with a maximum velocity of 5.1 x 105 m/s from a metal when illuminated by photons with a wavelength of 440 nm. Calculate:
a. The energy of the incident photons.
b. The work function of the metal.
c. The longest wavelength of light which will result in electron emission.
Assuming it possible to travel at 0.95 c to a star at a proper distance of 100 light years from earth, calculate the following:
a. how long the trip to the star would take from the perspective of the traveler.
b. the distance between the earth and the star from the perspective of the traveler.
A lighthouse that rises h1 = 43.6 ft above the surface of the water sits on a rocky cliff that extends $d$ = 20.0 ft from its base, as shown in the figure below. A sailor on the deck of a ship sights the top of lighthouse at an angle of $theta$ = 29...
