Radio waves are electromagnetic waves.

As it doesn't need medium to travel through

Sound waves are mechanical waves

Bec. it needs a medium to ravel through

Wave motion is considered as periodic motion

As its motion is repeated regularly in equal period of time

Water waves are transverse mechanical waves.

As medium particles vibrate along the direction of wave propagation

Sound waves are longitudinal waves.

As medium particles vibrate perpendicular to the direction of wave propagation

We see lightning before hearing thunder.

Light is faster than sound

Astronauts use wireless devices to talk to each other on Moon.

Bec. sound is a mechanical wave that can not travel through space

As the frequency of the wave increases, its wavelength decreases.

Bec. they are inversely proportional to each ther

We can’t hear the sound of solar explosions, while we can see the light coming out of it

Bec. sound can not travel through space but light can

The motion of rotary bee is considered as a periodic motion, but is not considered as an oscillatory motion

Bec. it repeats its motion but not on both sides of its rest point

It is the maximum displacement achieved by the medium particles away from their rest positions.

Amplitude

It is the motion of an oscillating body when it passes by a fixed point on its path two successive times in the same direction.

One complete oscillation

The highest point in the transverse wave.

Crest

The area in the longitudinal wave at which the medium particles are faraway from each other.

Rarefaction

Time taken by the oscillating body to make one complete oscillation.
