Question

What property of light does NOT change when traveling through different mediums? a. Wavelength b. Direction c. Energy d. Index of Refraction What property of light interferes when light waves overlap? a. Wavelength b. Intensity c. Frequency d. Electric Field Which of these is NOT used to create a colorful spectrum of dispersed light? a. A screen of tightly spaced slits b. suspended water droplets (c) A rectangular slab of plastic d. A triangular slab of plastic A single slit interference pattern a. Has the same intensity at all maximums. b. Is visible in double slit patterns. c. Is visible in diffraction grating patterns. d. Gives a bright spot when the path length difference is 1, 2, or 3 ... wavelengths. e. Does not work when the slit replaced by a hair.

Explanation / Answer

1) for the property of light

as the energy of light is conserved and it is dependent on the frequency

it will not change

c Energy

2)

the property which interferes is

d) Electric field

this gives a resultant electric field

3)

when light pass through rectangular slab of plastic , it will not get dispersed

hence ,

c)

4)

A single slit pattern is diffraction of light around the edges of small objects and corners

c)
