Answer to Question #120595 in Atomic and Nuclear Physics for ethan

Question

Can you verify my answer?
1. Scientists were originally confused by the photoelectric effect because they expected the ejection of electrons to be most greatly affected by the light’s
A. wavelength
B. speed
C. intensity
D. frequency
==> C?

2. The energy of a photon is directly proportional to its _____
==> frequency?

3. Max Plank developed a mathematical equation that described the intensity of the light spectrum produced by blackbody radiation. He did so by assuming that
A. the light emitted created an emission spectrum
B. classical physics was wrong
C. the energy of the “resonators” was quantized
D. the number of electrons was quantized
==> C?

Answer 1

1. C (Scientist thought more is the intensity of light,more will be the energy and hence electron get out of the surface easily but that was actually wrong thinking process as photon is not behave like classical particle)
2. Frequency (Formula is $E=h\nu$ ,where $h$ is Plank's constant and $\nu$ is the frequency of light,thus $E\propto \nu$ )
3. C
