Step 1
0 \times 10^8 \) m/s is the speed of light and \( \lambda = 652 \times 10^{-9} \) m is the wavelength of the light. Show more…

1. A laser emits light of frequency 4.74 x 10 raise to the power of 14 Hz. What is the wavelength of the light in nm? 2. What is the frequency of light waves with the wavelength of 5 x 10 raise to the power of -7 m? 3. A wave has frequency of 50 Hz and a wavelength of 10 m. What is the speed of the wave?

Calculate the wavelengths of (a) a 1.0 -MHz AM radio wave, (b) a channel 9 TV signal $(190 \mathrm{MHz}),$ (c) a police radar (10 GHz), (d) infrared radiation from a hot stove $\left(4 \times 10^{13} \mathrm{Hz}\right)$ (e) green light $\left(6.0 \times 10^{14} \mathrm{Hz}\right),$ and $(\mathrm{f}) 1.0 \times 10^{18}-\mathrm{Hz}$ X rays. All are electromagnetic waves that propagate at $3.0 \times 10^{8} \mathrm{m} / \mathrm{s}.$
