Question

on Helium | peach| 1 omplete the following for the row with the The numbers on the scale mark hundreds of nanometers. A mark at 5 would equal 500 nm. Convert your uler values to nm and record in the table. Convert the speed of light from 3.00 x 10* m/s to nm/s in the space below (use dimensional analysis) 仔 (o J.Calclate the frequency and energy for each line Remember, . lu and E-hw Show ll work on Se paralr shee value on the ruler wavelength (am)frequency (Hz) Source color nm

Answer 1

3)

for red :

wavelength = 680 nm

C = velocity of light = 3 x 10^8 m / s

frequency = C / lambda

                 = 3 x 10^8 / 680 x 10^-9

frequency = 4.41 x 10^14 Hz

Energy = h v

            = 6.625 x 10^-34 x 4.41 x 10^14

Energy = 2.92 x 10^-19 J

for orange :

waveength = 600 nm

frequency = 5.00 x 10^14 Hz

energy = 3.31 x 10^-19 J

for green :

frequency = 5.66 x 10^14 Hz

Energy = 3.75 x 10^-19 J

for blue :

frequency = 6.52 x 10^14 Hz

Energy = 4.32 x 10^-19 J
