Question

The source that illuminates the double slit in the double-slit interference experiment emits two distinct monochromatic waves of wavelength:

(a) Equal magnitude
(b) Different magnitudes
(c) Equal frequency
(d) Different frequencies

Answer 1

In the double-slit interference experiment, the source emits two distinct monochromatic waves of equal wavelength.

Step-by-step explanation:

The source that illuminates the double slit in the double-slit interference experiment emits two distinct monochromatic waves of wavelength:

1. (a) Equal magnitude
2. (b) Different magnitudes
3. (c) Equal frequency
4. (d) Different frequencies

In the double-slit interference experiment, both electrons and photons can be used as the source. In both cases, the waves have equal wavelengths. This is stated in Figure 29.22, which shows that the interference patterns for electrons and photons are identical when the wavelengths and slit separations are equal.
