Mechanical and Electromagnetic Waves

Front

What is the definition of a wave?

Back

A wave is a disturbance that transfers energy from one place to another without transferring matter.

Front

What is the formula to calculate the speed of a wave?

Back

Speed = Wavelength × Frequency.

Front

What is the relationship between wavelength and frequency?

Back

Wavelength and frequency are inversely related; as one increases, the other decreases.

Front

What is the period of a wave?

Back

The period is the time it takes for one complete cycle of the wave to pass a given point.

Front

How do mechanical waves differ from electromagnetic waves?

Back

Mechanical waves require a medium to travel through, while electromagnetic waves do not.

Front

What are the two main types of mechanical waves?

Back

Transverse waves and longitudinal waves.

Front

What is a transverse wave?

Back

In a transverse wave, the disturbance is perpendicular to the direction of wave motion.

Front

What is a longitudinal wave?

Back

In a longitudinal wave, the disturbance is parallel to the direction of wave motion.

Front

What is the speed of sound in air at room temperature?

Back

Approximately 343 m/s.

Front

What is the electromagnetic spectrum?

Back

The electromagnetic spectrum is the range of all types of electromagnetic radiation, from radio waves to gamma rays.
