Solution Verified by Toppr
Correct option is B)
Frequency of light wave = fFrequency of sound wave = f
∴ Wavelength of light waves λ
L =c/f ...(i)
where, c = velocity of light
and wavelength of sound waves λ
s =v/f
v = velocity of sound
∴ λ S λ L = v/f c/f = v c but c>>>v⇒ v c >>>1 ⇒ λ S λ L =λ L >>>λ S Video Explanation

Which has greater wavelength (sound or Light?
Aryan raj 30th Apr, 2020 Answer Answer later Report Answer (1) Neha Kanwar 1st May, 2020 Hello Aryan,
Sound and light both travel as waves. Sound waves travel a million times slower than light waves. Sound has greater wavelength as compared to the wavelength of light.
The wavelength and frequency are closely related whether it is sound or it is light. The higher the frequency, the shorter the wavelength.
Hope it clears your doubt.
Thank you!

Which has greater wavelength and frequency, sound waves or light waves?
Answer (1 of 6): The answers heretofore are surprisingly wrong or at least misleading. For any wave, the relationship that speed = wavelength times frequency holds. For sound at normal atmospheric pressure, the speed is about 330 m/s. The audible sound spectrum is 20 Hz to 20 kHz. Wavelengt...

Sound waves(mechanical waves) has longer wavelength than light(electromagnetic wave), Since wavelength has inverse relation with frequency so frequency of light (electromagnetic wave) is higher than sound (mechanical wave).

The answers heretofore are surprisingly wrong or at least misleading.
For any wave, the relationship that
speed = wavelength times frequency
holds.
For sound at normal atmospheric pressure, the speed is about 330 m/s.
The audible sound spectrum is 20 Hz to 20 kHz.
Wavelength of sound at 20 Hz is 16.5 meters.
Wavelength at 200 Hz is 1.65 meters.
Wavelength at 2 kHz is 0.165 meter.
Wavelength at 20 kHz is 16.5 cm.
–––––––––––––––––––––––––––––––––––––––
For light, speed is 300,000 km/second.
At 150 kHz, the bottom of the AM broadcast band (BCB) in Europe, wavelength is 2 km.
At 530 kHz, the bottom of the AM

Can the sound waves be seen if their frequency and wavelength are made equal to that of light spectrum (electromagnetic waves)?
Yep, the sound becomes visible …but only because sound is vibrating matter. When we vibrate matter at the frequencies of light, the electrons in the matter start emitting normal light!
But that’s cheating! We wanted to see the sound itself! Heh.
Unfortunately, at the wavelengths of visible light, matter starts behaving like individual atoms, not like a uniform material. So, the electrons get jostled, rather than riding along with the moving atoms, as they do during low-frequency sound. The sound becomes electrical. The electron-wiggles turned the sound waves into light itself.
Weirder idea: what
