Question 1

Which experiment provided the first strong evidence against the existence of the luminiferous aether as a medium for light propagation?

Accepted Answer

Michelson-Morley experiment

Question 2

Which property of light is responsible for the formation of rainbows in the sky?

Accepted Answer

Dispersion

Question 3

According to Maxwell's equations, what is light fundamentally composed of?

Accepted Answer

Oscillating electric and magnetic fields

Question 4

The wave equation for light is given by $$v = f \lambda. If $$the frequency of light is doubled in a vacuum, what happens to its wavelength?

Accepted Answer

It is halved

Question 5

Which of the following best explains why the Michelson-Morley experiment was considered a null result?

Accepted Answer

It failed to detect any difference in the speed of light due to Earth's motion through the aether

Question 6

Which of the following statements about the speed of light is correct?

Accepted Answer

It is constant in all directions in a vacuum

Question 7

A person is nearsighted (myopic). Where does the image of a distant object form in their eye, and how is this corrected?

Accepted Answer

Image forms in front of the retina; corrected with concave lenses

Question 8

Which property of light is primarily responsible for the phenomenon of interference patterns observed in the double-slit experiment?

Accepted Answer

Interference

Question 9

If white light passes through a prism, what happens to the different colors that make up the white light?

Accepted Answer

They are separated due to different wavelengths (dispersion)

Question 10

Which of the following best describes the relationship between wavelength and color in visible light?

Accepted Answer

Longer wavelengths correspond to red, shorter to violet

Question 11

Which cells in the human eye are primarily responsible for color vision?

Accepted Answer

Cones

Question 12

A police radar gun uses the Doppler effect to measure the speed of a car. Which property of light is being utilized in this scenario?

Accepted Answer

Doppler shift

Question 13

Which of the following is NOT a behavior of light explained by the wave model?

Accepted Answer

Photoelectric effect

Question 14

If the amplitude of a light wave increases, what change will be perceived by the human eye?

Accepted Answer

The brightness will increase

Question 15

Which of the following statements about the primary colors of light is correct?

Accepted Answer

They are red, green, and blue

Question 16

A farsighted (hyperopic) person has images forming behind the retina. Which type of lens is used to correct this condition?

Accepted Answer

Convex lens

Question 17

Which real-world application relies on the principle of light dispersion?

Accepted Answer

Prism-based spectrometers

Question 18

Which of the following best describes why light can travel through a vacuum?

Accepted Answer

It consists of oscillating electric and magnetic fields that do not require a medium

Question 19

If the frequency of visible light increases, what happens to its energy and color?

Accepted Answer

Energy increases and color shifts toward blue/violet

Question 20

Which historical measurement first provided a value for the speed of light using astronomical observations?

Accepted Answer

Roemer's observation of Jupiter's moons
