Quantum Radiation
1. The frequency of the incident photon after Compton effect will:
- A. Remain constant
- B. Increase
- C. Decrease
- D. None of these
View answer and explanation
Answer: C. Decrease
In Compton scattering the incident photon transfers part of its energy to the electron. Since photon energy is h times nu, losing energy means the scattered photon has lower frequency. It cannot stay the same or increase because energy is conserved in the collision.
Quantum Radiation
2. Curiosity Rover captured a flower like formation on the rocks of
- A. Venus
- B. Jupiter
- C. Saturn
- D. Mars
View answer and explanation
Answer: D. Mars
NASA's Curiosity rover photographed a flower-like mineral formation on the rocks of Mars. The rover has not operated on Venus, Jupiter or Saturn.
Quantum Radiation
3. Energy quantization was proposed by:
- A. Newton
- B. Einstein
- C. Planck
- D. Bohr
View answer and explanation
Answer: C. Planck
Max Planck introduced energy quantization ( in 1900 to explain black-body radiation (option C). Newton predates quantum theory, Einstein extended it to photons, and Bohr applied it to the atom.
