Question 1:

Which experiment provided evidence for the particle-like behavior of light?

A) Double-slit experiment
B) Photoelectric effect
C) Interference pattern
D) Diffraction pattern

Show Answer

Explanation: The correct answer is B) Photoelectric effect. The photoelectric effect, first observed by Heinrich Hertz and later explained by Albert Einstein, provided evidence for the particle-like behavior of light. The phenomenon involves the ejection of electrons from a material when illuminated by light of sufficiently high frequency.

Question 2:

Which experiment demonstrated the wave-like behavior of electrons?

A) Double-slit experiment
B) Photoelectric effect
C) Compton scattering
D) Stern-Gerlach experiment

Show Answer

Explanation: The correct answer is A) Double-slit experiment. The double-slit experiment, conducted with electrons by Clinton Davisson and Lester Germer, demonstrated the wave-like behavior of electrons. The experiment showed interference patterns when electrons passed through a double-slit, providing evidence for the wave-like nature of particles.

Question 3:

Which experiment confirmed the wave-particle duality of matter?

A) Davisson-Germer experiment
B) Stern-Gerlach experiment
C) Franck-Hertz experiment
D) Michelson-Morley experiment

Show Answer

Explanation: The correct answer is A) Davisson-Germer experiment. The Davisson-Germer experiment, performed in 1927, confirmed the wave-particle duality of matter. They observed diffraction patterns when electrons were scattered from a crystal surface, providing direct evidence for the wave-like nature of electrons.

Question 4:

Which experiment demonstrated the wave-particle duality of photons?

A) Double-slit experiment
B) Photoelectric effect
C) Stern-Gerlach experiment
D) Davisson-Germer experiment

Show Answer

Explanation: The correct answer is A) Double-slit experiment. The double-slit experiment, conducted with light, demonstrated the wave-particle duality of photons. When light passed through two closely spaced slits, it created an interference pattern on a screen, indicating the wave-like behavior of light particles (photons).

Question 5:

Which experiment revealed the wave-like behavior of electrons by demonstrating electron diffraction?

A) Compton scattering
B) Stern-Gerlach experiment
C) Davisson-Germer experiment
D) Millikan oil drop experiment

Show Answer

Explanation: The correct answer is C) Davisson-Germer experiment. The Davisson-Germer experiment, involving the scattering of electrons from a crystal surface, revealed the wave-like behavior of electrons by demonstrating electron diffraction. The observed diffraction patterns provided direct evidence for the wave nature of particles.
