A student using a diffraction grating ruled with 6.20 x 104 lines/m to measure the frequency of some monochromatic light. If the nodal lines are 0.0522 m apart at a distance of 1.50 m from the grating, what is the frequency of the light used? (5.3 x 1014 Hz) 12. Using the information in question 9, determine the distance between nodal lines if the frequency of the light was changed to four-fifths of its original while all other variables remained...
Light of frequency 5.0 x 1014 Hz falls on a diffraction grating which has 4.2 x 103 lines /cm. At what angle will the third antinodal line will be inclined to the forward direction? (49°)
just letter suffice . all 4 qs photon with a frequency of 2.5 x 1015 Hz strikes the surface of a metal. If the can be stopped by a voltage of 3.0 v, the work function of the metal is 41) An Ultraviolet electrons that are ejected be a. 5.3 eV and the photon has an energy o b. 8.2 eV and the photon has an energy of 1.3 x 10s Joules c. 5.3 eV and the photon has an...
