Answer :
Answer:These answers should align with the principles of quantum mechanics and the experimental observations typically associated with the double-slit experiment.
Explanation:Which of the following supports the wave nature of electrons?
A. Blue light is used in a double-slit experiment.
B. X-rays are used in crystallization.
C. Water is heated to 1000°C in a pot.
D. An electron enters a parallel plate capacitor which deflects the electron downward.
Answer: A. Blue light is used in a double-slit experiment.
The double-slit experiment with light demonstrates interference patterns characteristic of wave behavior, supporting the wave nature of light. Similarly, electrons exhibit interference patterns in a double-slit experiment, indicating their wave-like behavior.
What is the importance of projecting electrons one at a time in the conduct of the double-slit experiment?
A. The detector needs time to reset to detect the next electron.
B. The slits are too narrow to allow two electrons to pass at the same time.
C. This prevented the electrons from interacting with each other.
D. Time is needed to generate more electrons.
Answer: C. This prevented the electrons from interacting with each other.
By projecting electrons one at a time, you ensure that each electron passes through the slits without interference from another electron. This allows the observation of individual electron interference patterns, demonstrating the wave-like behavior of electrons.
Which will not happen to electrons based on the double-slit experiment?
A. They sometimes behave like waves and particles.
B. They split in half and go through both slits simultaneously.
C. They behave like particles, but they are waves.
D. They are both waves and particles at the same time.
Answer: B. They split in half and go through both slits simultaneously.
According to quantum mechanics and the double-slit experiment, electrons do not split in half and pass through both slits simultaneously. Instead, they exhibit interference patterns characteristic of wave-like behavior when passing through the slits one at a time.
Which is seen on the screen detector in the electron double-slit experiment?
A. White bands
B. Dark bands
C. Monochromatic light
D. Alternating white and dark bands
Answer: D. Alternating white and dark bands
The interference pattern observed on the screen detector in the electron double-slit experiment consists of alternating bright and dark bands. This pattern is a hallmark of wave interference and supports the wave nature of electrons.
Which of the following observations in the double-slit experiment led to the conclusion that electrons behave like waves?
A. Electrons spread-out
B. Electrons form diffraction patterns
C. Electrons build up an interference pattern
D. Electrons remain at specific locations and build up a distribution pattern
Answer: C. Electrons build up an interference pattern
The observation that electrons build up an interference pattern on the detector screen in the double-slit experiment led to the conclusion that electrons behave like waves. This interference pattern occurs due to the superposition of electron waves passing through the slits, confirming their wave-like nature.
