transverse : light
longitudinal : sound
transverse : up & down
longitudinal : left & right or side to side
transverse : perpendicular
longitudinal : parallel
transverse : up & down ocean wave
longitudinal : archer pulling back on a bowstring then letting go releasing the string
v = λf : speed of a wave is measured in meters per second (m/s), the wavelength is measured in meters (m), and the frequency is measured in hertz (Hz)
ANSWER:
A transverse wave has the displacement perpendicular (i.e., at right angles) to the direction of wave propagation. An example of a transverse wave is the wave on a string, where the displacement of the string is perpendicular to the direction in which the wave travels.
A longitudinal wave (also known as a compression wave or pressure wave) has the displacement parallel to the direction of wave propagation. An example of a longitudinal wave is sound waves, where the particles of the medium vibrate parallel to the direction of the wave as the wave travels through the medium.

Transverse waves:
The displacement of the wave is perpendicular to the direction of wave propagation.
Example: A wave on a string, where the string moves up and down while the wave moves left and right.
Simple analogy: Imagine shaking a jump rope up and down while holding it horizontally - the wave travels horizontally while the rope moves up and down.
Longitudinal waves:
The displacement of the wave is parallel to the direction of wave propagation.
Example: Sound waves, where air molecules move back and forth in the same direction as the wave.
Simple analogy: Imagine squeezing a slinky in a direction parallel to the slinky - the wave travels in that same direction while the slinky compresses and expands.
Formula used: There is no specific formula for describing the direction of wave displacement, as it depends on the type of wave. However, the speed of a wave can be calculated using the formula v = λf, where v is the speed of the wave, λ (lambda) is the wavelength, and f is the frequency.
Real-world example: Light waves are transverse waves, with the electric and magnetic fields perpendicular to the direction of propagation. This can be seen in polarization filters, which only allow light waves with a certain orientation of electric field to pass through.
Real-world example of longitudinal waves
An example of longitudinal waves in the real world is sound waves, which are pressure waves that propagate through a medium such as air, water, or solids. Sound waves are longitudinal waves because the vibrations of air molecules or particles in a medium are parallel to the direction of the wave's propagation. Examples of sound waves in daily life include the sound of a car engine, a musical instrument, or a person speaking.
