Types of Wave

The video tutorial explains wave motion, classifying it into two types based on energy transfer and vibration direction. It distinguishes between mechanical waves, which require a medium, and electromagnetic waves, which do not. The tutorial further explores transverse waves, characterized by crests and troughs, and longitudinal waves, characterized by compressions and refractions. It concludes with a discussion on measuring wave properties, including wavelength, amplitude, velocity, frequency, and periodic time, and introduces the law relating wave velocity, frequency, and wavelength.

What are the two main criteria used to classify wave motion?

• Shape of wave; sound of wave

• Ability to propagate and transfer energy; direction of vibration relative to propagation

• Speed of wave; color of wave

• Temperature of medium; size of wave

Which type of wave requires a medium to propagate?

• Longitudinal waves

• Mechanical waves

• Electromagnetic waves

• Transverse waves

What is a characteristic of transverse waves?

• They consist of crests and troughs

• They vibrate parallel to the direction of propagation

• They consist of compressions and rarefactions

• They require a vacuum to propagate

What is the unit of measurement for wave frequency?

• Meters

• Seconds

• Hertz

• Meters per second

Which law describes the relationship between wave velocity, frequency, and wavelength?

• Wave Equation

• Ohm's Law

• Newton's Law

• Hooke's Law
