difference between light waves and sound waves ...plz give atleast 3 points in a tabular form......

Answered by arshad4286

Sound and light both travel in waves, which are caused by vibrations. The vibrations begin when an object at rest is set in motion (e.g. a guitar string or electrons). This vibrating motion can begin (initial displacement) in two ways, longitudinal or transverse. Light waves are transverse. This is when the movement of electrons is perpendicular to the motion of the wave. An example is a football stadium wave. Everyone is waiting for their turn, and when it comes, they sit and stand in an up and down motion, and the wave continues forward. Light waves, therefore, move faster than sound waves, which are longitudinal. Light waves can also travel through space.

arshad4286: Plz mark me brilliant answer

saniaseraj: yeah.. i would but I read ur ans

saniaseraj: ur ans doesn't give me the difference but gives me the similitaries...

saniaseraj: :(

arshad4286: Is it any mistake in answer

arshad4286: Although both are forms of wave motion, sound requires a solid, liquid, or gaseous medium; whereas light travels through empty space. The denser the medium, the greater the speed of sound. ... Sound travels through all substances, but light cannot pass through opaque materials. Frequency affects both sound and light.

saniaseraj: ok.. th k

saniaseraj: thnx
