Answer 41

Wavelength * frequency = speed of light

Wavelength = (3 x 10⁸ m/s)/(1.365 x 10⁶ s^-1)

= 2.19 x 10² m

Answer 42

Energy = Planck's constant x frequency

= (6.626 x 10^-34 J s) x (1.258 x 10¹⁰ s^-1)

= 8.335 x 10^-24 J

Answer 43

Energy =2.18 x 10^-18 [(1/n_f²) - (1/n_i²)]

=2.18 x 10^-18 [(1/2²) - (1/4²)]

= 4.09 x 10^-19 J

Frequency = Energy / Planck's constant

= 4.09 x 10^-19/6.626 x 10^-34

= 6.17 x 10¹⁴ s^-1

Answer 44

Wavelength = Planck's constant/(mass * velocity)

= (6.626 x 10^-34 Js)/(1.675 x 10^-27 kg * 7.48 m/s)

= 5.29 x 10^-8 m
