Question

v= c/a. E = hv c = 2998 x 10°mis n = 6.626 2x10-34 JS 6. What is the energy of a 7.66 x 1014 Hz wave? 7. What is the frequency of a wave carrying 8.35 x 10-18 J of energy? 8. What is the frequency of a 1.78 x 10-15 J wave? 9. What is the energy of a 3.12 x 1018 s 2 wave? 10. What is the frequency of a 1.31 x 10-22 J wave? What is its wavelength?

Answer 1

as we all know E= the Clu or g. = 777x10145 Hz Freq = EF - 5.525 X 10 34 x 7.77 xloly - 5.140%.10- og Energy of the wave - 5.15x15 19 J E- 8.35 x 10-10J 2= Elt = 8.35 X10-16 - = 1.25 X 10 15 Hz 5.GR6 X10-34 - Ans Freq. of wave = 1125x10 to Hz EF 1070 x 10-15'T Lop 2- Elh = 179 X10-15 I 6.626 X10-34 J/5 = 2:69x1010 S-1

-34 43112x109 - 3.12 xlola 51 E= 2 = 6.626 X10-34 Xaus = 2.07 x 10-15 g Er 1.31 X10-22 J - Elh = 1131x10-22 T 6.626 X10 34 IS = 1.98 xion 57 = c/ r = [/25 v3x10 m 15 = 1.51x10m ligo Xo!! 5-7 I= 1.51 x 10-3 m.
