Question

Electromagnetic Waves A certain helium-neon laser emits red light in a narrow band of wavelengths centered at 632.8 $\mathrm{nm}$ and with a "wavelength width" (such as on the scale of Fig. 33-1) of 0.0100 $\mathrm{nm} .$ What is the corresponding "frequency width 'for the emission?

Step 1

Given: Wavelength, $\lambda = 632.8 \, \text{nm} = 632.8 \times 10^{-9} \, \text{m}$ Speed of light, $c = 3.00 \times 10^8 \, \text{m/s}$ Substitute the values into the formula: $f = \frac{3.00 \times 10^8 \, \text{m/s}}{632.8 \times 10^{-9} \, \text{m}}$ $f = Show more…
