Question

Which of the following undergoes largest diffraction?a)Ultraviolet lightb)Infra red lightc)Radio wavesd)Y &#8211; raysCorrect answer is option 'C'. Can you explain this answer?

Answer

Maximum diffraction occurs when size of obstacle is almost equal to wavelength of light wave. Hence maximum diffraction occurs for larger wavelength . As wavelength of radio wave is higher than others, maximum diffraction will occur for it.

Answer

Diffraction occurs with all waves, including sound waves, water waves, and electromagnetic waves such as visible light, X-rays and radio waves.For the diffraction of wave an obstacle or aperture of the size of wavelength of the wave is needed.Since the wavelength of radio wave is large and comparable with the size of the obstacles around which they bend.lt shows maximum diffraction.

Answer

Diffraction is the bending or spreading of waves as they encounter an obstacle or pass through an aperture. The degree of diffraction depends on the wavelength of the wave and the size of the obstacle or aperture. The larger the wavelength or the smaller the obstacle or aperture, the greater the diffraction.

- Ultraviolet light:
Ultraviolet (UV) light has a wavelength range of 10 nm to 400 nm. It falls in the range of electromagnetic waves between X-rays and visible light. Although UV light has a shorter wavelength compared to visible light, it undergoes less diffraction than radio waves because the obstacles or apertures encountered are generally larger than the wavelength of UV light.

- Infra-red light:
Infrared (IR) light has a wavelength range of 700 nm to 1 mm. It falls in the range of electromagnetic waves between visible light and microwaves. Like UV light, IR light undergoes less diffraction compared to radio waves due to its shorter wavelength.

- Radio waves:
Radio waves have a wavelength range of 1 mm to 100 km. They have the longest wavelength among the options given. Radio waves easily undergo diffraction due to their large wavelength and can bend around obstacles or spread out when passing through small openings. This is why radio waves are commonly used for long-range communication and can be received even when the transmitter is not directly in the line of sight.

- Y rays:
It is important to note that 'Y rays' is not a recognized term in the field of electromagnetic waves. It is possible that it is a typo or a misinterpretation of another term. If we assume 'Y rays' refers to gamma rays, then gamma rays have a wavelength range of less than 0.01 nm. They have the shortest wavelength among the options given. Gamma rays do not undergo significant diffraction as their wavelength is much smaller than the size of any obstacle or aperture encountered.

Therefore, among the given options, radio waves undergo the largest diffraction due to their long wavelength.
