100% Pass
Which of the following questions can wave optics provide answers to? - ANS Why are clouds
and ocean surf white?, Why do polarized sunglasses reduce reflected glare?, What causes the
beautiful colors in a soap bubble or an oil film?, Why is the sky blue?
Young's double slit experiment demonstrates - ANS diffraction.
The technology behind noise-cancelling headphones leverages - ANS destructive
interference.
We can attribute the wave theory of diffraction to - ANS Fresnel
The angle of incidence at which reflected light is 100% polarized is known as. -
ANS Brewster's angle.
Every point on a wavefront may be considered the source of secondary wavelets that spread
out in all directions with a speed equal to the speed of propagation of the waves. -
ANS Huygens' principle
The bending of light that passes near the edge of an object or through a narrow slit, causing the
light to spread. - ANS Diffraction

The overlapping and combining of waves. - ANS Superposition
The result of superposing different waves, usually of the same wavelength. Constructive
interference results from crest-to-crest reinforcement; destructive interference results from
crest-to-trough cancellation. The interference of selected wavelengths of light produces colors
known as interference colors. - ANS Interference
The alignment of the transverse electric vibrations of electromagnetic radiation. Such waves of
aligned vibrations are said to be polarized. - ANS Polarization
A two-dimensional microscopic interference pattern that shows three-dimensional optical
images. - ANS Hologram
The superposition of waves can produce - ANS reinforcement, cancellation, partial
cancellation
The superposition of identical waves affects - ANS amplitude.
The wave-particle duality applies to - ANS photons, electrons, protons
After passing through double slits, electrons make a pattern on a screen that -
ANS resembles a pattern that waves make.
Light from two closely spaced stars cannot produce a steady interference pattern due to -
ANS Incoherence
In the double slit experiment, fringes are more widely spaced when illumination is with
monochromatic (single color) - ANS longer wavelength light
