Why is sound wave a longitudinal wave?

Sound waves in air (and any fluid medium) are longitudinal waves because particles of the medium through which the sound is transported vibrate parallel to the direction that the sound wave moves.

Wavelength is the distance between 2 crests or troughs on adjacent wave .Measured in meters.

Why is light a transverse wave?

Light is a transverse wave because its components vibrate perpendicular to the direction of propagation. A transverse wave is a wave that oscillates perpendicular to its direction of propagation. It has an electric and a magnetic component.

Wave can be described  as an oscillation accompanied by a transfer of energy that travels through a medium (space or mass). Frequency refers to the addition of time.

What is the diffrence between waves and tides?

~Tides are formed because of the interaction of the gravitational forces between the Earth, the moon, and the sun. Waves are formed because of the gusting or raging force exerted by the wind on the water surface.
