Why can we readily observe diffraction effects for sound waves and water waves, but not for light? Is this because light travels so much faster than these other waves? Explain.
The explanation for the diffraction effects can be observed for sound waves and water waves but not for light. Whether this is because light travels so much faster than these other waves.
Explanation of Solution
The light waves have very short wavelength as compare to the wavelength of the sound waves and water waves. Due to this light waves undergo very little diffraction which cannot be observed.
The diffraction of a wave depends on the wavelength of the wave. The larger will be the wavelength the more the diffraction is easily observed because commonly available apertures are of the size of the wavelength of sound waves. As the wavelength of the light is very small, the diffraction in the light is not easily observed because commonly available apertures are not of the size of the wavelength of light waves.
Conclusion:
Therefore, the diffraction effect cannot be observed for light waves because the light carries very shorter wavelength.

- Many cells are transparent anti colorless. Structures of great interest in biology and medicine can be practically invisible to ordinary microscopy. To indicate the size and shape of cell structures, an interference micro-scope reveals a difference in index of refraction as a shift in interference fringes. The idea is exemplified in the following problem. An air wedge is formed between two glass plates in contact along one edge and slightly separated at the opposite edge as in Figure P37.37. When the plates are illuminated with monochromatic light from above, the reflected light has 85 dark fringes. Calculate the number of dark fringes that appear if water (n = 1.33) replaces the air between the plates.arrow_forwardTwo closely spaced wavelengths of light are incident on a diffraction grating. (a) Starting with Equation 37.7, show that the angular dispersion of the grating is given by dd=mdcos (b) A square grating 2.00 cm on each side containing 8 000 equally spaced slits is used to analyze the spectrum of mercury. Two closely spaced lines emitted by this element have wavelengths of 579.065 nm and 576.959 nm. What is the angular separation of these two wavelengths in the second-order spectrum?arrow_forwardWhat If?

Hint: Assume that the first-order maximum is halfway between the first- and second-order minima.arrow_forwardA laser beam with vacuum wavelength 632.8 nm is incident from air onto a block of Lucite as shown in Figure 35.10b.

- A film of oil on water will appear dark when it is very thin, because the path length difference becomes small compared with the wavelength of light and there is a phase shift at the top surface. If it becomes dark when the path length difference is less than one-fourth the wavelength, what is the thickest the oil can be and appear dark at all visible wavelengths?
