Question

v=c/ C = 2,998 x 108 m/s E = hv h = 6.626 2 x 10-34 Js 1. What is the wavelength of a wave having a frequency of 3.76 x 1014 s-?? 2. What is the frequency of a 6.9 x 10-18 m wave? 3. What is the wavelength of a 2.99 Hz wave? 4. What is the wavelength of a 1.28 x 1017 Hz wave? 5. What is the frequency of a 7.43 x 10 m wave?

Answer 1

and . Ezha E=h2 V = Enequency of a ware fa wavelength of the coase; c= velocity of light ha blanck's constant = 3 x 108 mis : E a Emergy of the care 1. Chivem, biequency, w = 3.76x1045-'. wavelength 990? headlight on, a se ni pogon 4x10 m/s or, 9 = 2.76x1014 S-1 0.798x10 m ... The wavelength of the ware is 0.798% 100 m - 6 . . Given, warelengths a: 6.9x10-13 cm d e frequency, Viz? astees from the equation, 3x108 m/s 6.9*10-19 m 21 0.4347 x 10 the wave is 0.4347 x 1021 m The frequency

3. riven, V=2.99 Hz = 2.99.51 from the given equations & C 1 9X108 m/s - 2.995 1003x108 m . is 1.003 x109 m The wavelength A: herem, v= 1.28 x10 Hz ... from the given equation we gek, da - 3x108 m/s 1.28*10'7 s-1 = 2.343 x 10 5) barem, waselength, A = 7.48 x 10-5m . from the giren equation, we get 2000 3X108 - 7.43 x 10-5 = 0.403 x 103 m frequency is 0.403x1013 m.
