Photons are described as individual energy packets of:

  1. Electromagnetic waves
  2. Sound pressure waves
  3. Ocean surface waves
  4. Seismic ground waves
Show answer and solution

Correct answer: A. Electromagnetic waves

1. Light is treated as coming in discrete pieces. 2. Energy transfer occurs when photons are absorbed or emitted. 3. Photons are individual energy packets of electromagnetic waves. 4. Their energy is set by the frequency of the light wave. _Source: OpenStax College Physics for AP Courses 2e (CC BY 4.0), Ch 29 'Quantum Physics', sections 29.1-29.8_

In the photon energy equation, the letter h stands for:

  1. The hour elapsed
  2. Planck's constant
  3. The wave height
  4. The heat capacity
Show answer and solution

Correct answer: B. Planck's constant

1. The equation has two named quantities besides energy. 2. Photon energy is written as E equals h times f. 3. In that equation h is Planck's constant. 4. The letter f is the frequency of the associated light wave. _Source: OpenStax College Physics for AP Courses 2e (CC BY 4.0), Ch 29 'Quantum Physics', sections 29.1-29.8_

In the photon energy equation, the letter f stands for the:

  1. Frequency of the wave
  2. Force on the wave
  3. Focal length used
  4. Field strength found
Show answer and solution

Correct answer: A. Frequency of the wave

1. The second symbol describes the light itself. 2. Photon energy is h times f. 3. The letter h is Planck's constant. 4. The letter f is the frequency of the associated light wave. _Source: OpenStax College Physics for AP Courses 2e (CC BY 4.0), Ch 29 'Quantum Physics', sections 29.1-29.8_
