The video tutorial explains energy transfer through mechanical waves, focusing on transverse and longitudinal waves. It covers key concepts like medium, equilibrium, crest, trough, wavelength, amplitude, compression, and rarefaction. The tutorial also introduces the wave speed formula, demonstrating how to calculate wave velocity, wavelength, and frequency using examples.

What does the medium do as the wave passes through it?

• Creates new energy

• Transfers energy to another medium

• Moves with the wave

• Does not move along with the wave

What direction do the vibrations occur in a transverse wave relative to the wave direction?

• Parallel

• Perpendicular

• At a 45-degree angle

• Randomly

What is the amplitude of a wave?

• The total energy of the wave

• The highest point of the wave

• The distance from the crest to the equilibrium

• The length of the wave

What is a rarefaction in a longitudinal wave?

• The highest energy point

• The closest point of particles

• The point where particles are furthest apart

• The beginning of the wave

What causes a longitudinal wave?

• Vibration perpendicular to the wave direction

• Vibration in the same direction as the wave travels

• External atmospheric pressure

• Electrical impulses

What does the wave speed formula calculate?

• The color of the wave

• The energy of the wave

• The frequency of the wave

• The speed or velocity of the wave

How can the speed of a wave be increased according to the wave speed formula?

• By decreasing the frequency

• By reducing the amplitude

• By increasing the wavelength

• By increasing the frequency or wavelength

What unit is used to measure the frequency of a wave?

• Meters

• Newton

• Hertz

• Seconds

If a wave has a frequency of 2 Hz and is moving at 4 m/s, what is its wavelength?

• 1 meter

• 0.5 meters

• 8 meters

• 2 meters
