Directions: These questions consist of two statements, each printed as Assertion and Reason. While answering these questions, you are required to choose any one of the following four responses.
Assertion : Diffraction takes place for all types of waves mechanical or nonmechanical, transverse or longitudinal.
Reason : Diffraction’s effects are perceptible only if wavelength of wave is comparable to dimensions of diffracting device.
  • a)
    If both Assertion and Reason are correct and the Reason is a correct explanation of the Assertion.
  • b)
    If both Assertion and Reason are correct but Reason is not a correct explanation of the Assertion.
  • c)
    If the Assertion is correct but Reason is incorrect.
  • d)
    If both the Assertion and Reason are incorrect.
Correct answer is option 'B'. Can you explain this answer?

Diffraction is defined as the bending of light around the corners of the obstacle or aperture into the region Of geometrical shadow if the obstacle. Diffraction occurs with all waves, including sound waves, water waves and electromagnetic waves.

Understanding the Assertion
The assertion states that "Diffraction takes place for all types of waves - mechanical or nonmechanical, transverse or longitudinal."
- Correctness: This is indeed true. Diffraction is a wave phenomenon that occurs when waves encounter an obstacle or a slit that is comparable in size to their wavelength. This applies to all types of waves, including sound waves (mechanical) and light waves (non-mechanical).
Explaining the Reason
The reason provided is: "Diffraction’s effects are perceptible only if the wavelength of the wave is comparable to the dimensions of the diffracting device."
- Correctness: This statement is also true. The effects of diffraction are most noticeable when the size of the obstacle or aperture is similar to the wavelength. If the obstacle is much larger than the wavelength, the diffraction effects become negligible.
Relationship Between Assertion and Reason
- Connection: While both statements are correct, the reason does not explain why diffraction occurs for all types of waves. The assertion encompasses a broader principle about the universality of diffraction across all wave types, while the reason focuses on the conditions necessary for observing diffraction effects.
Conclusion
Therefore, the correct option is B: "If both Assertion and Reason are correct but Reason is not a correct explanation of the Assertion." This choice accurately reflects the relationship between the two statements.

Read the following text and answer the following questions on the basis of the same:Diffraction in a hall:A and B went to purchase a ticket of a music programme. But unfortunately only one ticket was left. They purchased the single ticket and decided that A would be in the hall during the 1st half and B during the 2nd half.Both of them reached the hall together. A entered the hall and found that the seat was behind a pillar which creates an obstacle. He was disappointed. He thought that he would not be able to hear the programme properly.B was waiting outside the closed door. The door was not fully closed. There was a little opening.But surprisingly, A could hear the music programme.This happened due to diffraction of sound.The fact we hear sounds around corners and around barriers involves both diffraction and reflection of sound.Diffraction in such cases helps the sound to "bend around" the obstacles.In fact, diffraction is more pronounced with longer wavelengths implies that we can hear low frequencies around obstacles better than high frequencies.B was outside the door. He could also hear the programme. But he noticed that when the door opening is comparatively less he could hear the programme even being little away from the door. This is because when the width of the opening is larger than the wavelength of the wave passing through the gap then it does not spread out much on the other side. But when the opening is smaller than the wavelength more diffraction occurs and the waves spread out greatly – with semicircular wavefront. The opening in this case functions as a localized source of sound.Q. Diffraction of sound takes place more when
