Question 1
The wave nature of light was first proposed in 1678 by:
- AChristiaan Huygens
- BIsaac Newton
- CThomas Young
- DJames Clerk Maxwell
Show answerHide answer
Answer: A
Christiaan Huygens first proposed the wave nature of light in 1678.
Question 2
Newton's theory about the nature of light was:
- AWave theory
- BElectromagnetic theory
- CCorpuscular (particle) theory
- DQuantum theory
Show answerHide answer
Answer: C
Newton proposed the corpuscular nature of light and his theory was more famous and accepted at that time.
Question 3
Which experiment performed in 1801 proved the wave nature of light?
- ANewton's rings experiment
- BYoung's interference experiment
- CBragg's experiment
- DRubens tube experiment
Show answerHide answer
Answer: B
Young's interference experiment of 1801 established Huygens' wave theory.
Question 4
In 1860 Maxwell considered light to be:
- AStreams of corpuscles
- BSound waves
- CMechanical waves needing a medium
- DElectromagnetic waves
Show answerHide answer
Answer: D
Maxwell proposed that light consists of electromagnetic waves that can propagate through vacuum.
Question 5
The quantum explanation shows that light interacts with matter as discrete massless particles called:
- APhotons
- BElectrons
- CProtons
- DNeutrons
Show answerHide answer
Answer: A
Light propagates as an electromagnetic wave but interacts with matter as photons.
