Wave Properties and Behavior

This video tutorial introduces the concept of waves, explaining their basic properties such as wavelength, displacement, and amplitude. It further delves into the time period and frequency of waves, providing a clear understanding of how to calculate wave velocity using the equation v = fλ. The tutorial also includes practical examples to illustrate these concepts, making it easier for learners to grasp the fundamentals of wave motion.

What is a wave defined as?

• A circular motion in a vacuum

• A static line in space

• A disturbance in any medium

• A constant motion in a medium

What is the term for the highest point of a wave?

• Wavelength

• Trough

• Amplitude

• Crest

How is wavelength defined?

• The time for one complete oscillation

• The distance between two consecutive crests or troughs

• The maximum displacement from the undisturbed position

• The number of waves passing a point in one second

In the context of waves, what does 'amplitude' refer to?

• The distance between two crests

• The maximum displacement from the undisturbed position

• The time for one complete oscillation

• The number of waves passing a point in one second

What does the time period of a wave represent?

• The speed of the wave

• The maximum height of a wave

• The time required for one complete oscillation

• The distance between two points on a wave

What is the relationship between frequency and time period?

• They are equal

• Frequency is the square of the time period

• Frequency is the reciprocal of the time period

• They are unrelated

What is the unit of frequency?

• Hertz

• Seconds

• Newtons

• Meters

What is the formula for wave velocity?

• v = λ / f

• v = f / λ

• v = fλ

• v = λf²

If the frequency of a wave is 1 Hz and the wavelength is 1 meter, what is the velocity?

• 1.5 meters per second

• 2 meters per second

• 1 meter per second

• 0.5 meters per second

What happens to the velocity of a wave if the frequency is increased?

• The velocity decreases

• The velocity becomes zero

• The velocity remains the same

• The velocity increases
