Nov 24, 2023 · Visible light has a wavelength of range from 400-700nm, Violet light has a wavelength of 400nm whereas red light has a wavelength of 700nm. The wavelength of sound frequencies audible to the human ear is approximately 17 m and 17 mm.
Longitudinal waves are mechanical waves that require a medium for propagation, but transverse waves are non-mechanical waves that do not require a medium for propagation. Longitudinal waves consist of compressions and rarefactions, while transverse waves consist of crests and troughs. Q3.

light waves and sound waves can both be diffracted, reflected & refracted; they can both have a range of frequencies and wavelengths; they both transfer energy without transferring matter; Differences. sound waves are longitudinal and light waves are transverse; light travels much faster than sound
Finally, we need to say two things about light perception. For sound, intensity (proportional to amplitude-squared) is perceived as loudness, and for light it is brightness. For sound, frequency is perceived as pitch, and for visible light it is perceived as color.
Waves may be transverse, longitudinal, or a combination of the two. The waves on the strings of musical instruments are transverse (as shown in Figure 13.5), and so are electromagnetic waves, such as visible light. Sound waves in air and water are longitudinal. Their disturbances are periodic variations in pressure that are transmitted in fluids.
