Both light and sound waves produce diffraction. It is more difficult to observe the diffraction with light waves becausea)Light wave do not require mediumb)Wavelength of light waves is far smallerc)Light waves are transversed)Speed of light is far greaterCorrect answer is option 'B'. Can you explain this answer?

Question

Answer

For diffraction to occur, the width of the slit should be comparable with the wavelength of the wave. The wavelength of light wave is extremely short and slits with width comparable to that of light wave wavelength are quite rare. Hence it's difficult to observe diffraction with light waves.

Answer

In our macroscopic world, objects have size comparable to the wavelength of sound, therefore diffraction with light is difficult to observe.Wavelength of light is in the order of hundreds of nanometre which is a very smaller value.Hence, option B is correct.

Answer

B

Answer

Explanation:

Wavelength of light waves is far smaller:
- The diffraction of a wave is directly related to its wavelength.
- Light waves have much smaller wavelengths compared to sound waves.
- The smaller the wavelength, the less noticeable the diffraction effect will be.
- Light waves, with wavelengths in the range of 400-700 nanometers, exhibit minimal diffraction effects that are harder to observe.

Diffraction with light waves:
- Light waves can diffract when they encounter obstacles or pass through narrow openings.
- However, due to their small wavelength, the diffraction patterns produced by light waves are more subtle and harder to detect.
- In contrast, sound waves, with larger wavelengths, produce more noticeable diffraction effects, making them easier to observe.

Importance of wavelength:
- The wavelength of a wave determines its diffraction characteristics.
- Sound waves, with wavelengths in the range of meters to centimeters, diffract easily and exhibit clear diffraction patterns.
- Light waves, with much smaller wavelengths, have less pronounced diffraction effects, making them more challenging to observe.
Therefore, it is more difficult to observe diffraction with light waves compared to sound waves due to the significantly smaller wavelength of light waves.
