Question

Which best explains how the diffraction pattern observed in Young’s experiment supports the wave theory of light?
A. The pattern was caused by light moving in a straight path.
B.The pattern was caused by light being separated into colors.
C. The pattern was caused by the interference of waves.
D. The pattern was caused by the reflection of waves.

2 Answer

  • C. The pattern was caused by the interference of waves. 
  • Answer: The correct answer is option C.

    Explanation:

    The experiment performed by Thomas Young was named as double-slit experiment. In this experiment, he demonstrated the wave theory of the light.

    In the experiment, he took a point source of light which illuminated two narrow adjacent slits on the screen and the image formed by the light were passed through the slits and was observed on the second screen.

    The regions of dark and light regions were called as interference fringes which were caused by the constructive and the destructive interference of light waves.

    Hence, he concluded that the pattern that was caused was due to the interference of the waves.

    Therefore, the correct answer is Option C.
