Questions: 20 | Attempts: 10 | Last updated: Feb 13, 2026

Sample Question 1
In wireless communication, what is the primary purpose of a "Carrier Wave"?

To provide a high-frequency signal that can be modulated to carry information.

To act as the physical wire that connects two distant points.

To eliminate the need for an antenna at the receiving end.

To convert digital data directly into sound waves for air travel.

To amplify the battery life of the mobile device.

Sample Question 2
Frequency Modulation (FM) is more susceptible to atmospheric noise than Amplitude Modulation (AM).

True

False

Light’s Double Life: Photoelectric Effect Wave Particle Duality

Is light a wave or a stream of tiny bullets? When light hits a metal surface and knocks electrons loose, it proves that "particles" of light are at work. This photoelectric effect wave particle duality quiz tackles...

Questions: 20 | Attempts: 10 | Last updated: Feb 13, 2026

Sample Question 1
According to the photoelectric effect, what happens to the maximum kinetic energy of emitted electrons if the frequency of incident light increases?

It decreases

It remains constant

It increases

It drops to zero

It doubles exactly

Sample Question 2
