Wave Speed, Wavelength, and Frequency: Understanding their Relationship

The video tutorial explains the relationship between wave speed, wavelength, and frequency. It introduces the concept of transverse waves and describes how wave speed is calculated using distance and time. The tutorial provides examples, such as a surfer on a wave, to illustrate these calculations. It further explains how wave speed can be derived from wavelength and frequency, using equations and examples like ripples in a pond and seismic waves. Finally, it demonstrates how to calculate frequency from wave speed and wavelength, using sound waves as an example.

What is the relationship between the oscillating direction and propagation direction in a transverse wave?

• They are parallel to each other.

• They are in the same direction.

• They are at 45 degrees to each other.

• They are perpendicular to each other.

How is wave speed calculated using distance and time?

• Speed equals time minus distance.

• Speed equals time divided by distance.

• Speed equals distance divided by time.

• Speed equals distance multiplied by time.

In the surfer example, what is the speed of the wave if the surfer travels 15 meters in 4 seconds?

• 3.75 meters per second

• 4.5 meters per second

• 5 meters per second

• 3 meters per second

How is wave speed related to wavelength and frequency?

• Wave speed equals frequency minus wavelength.

• Wave speed equals wavelength divided by frequency.

• Wave speed equals frequency divided by wavelength.

• Wave speed equals wavelength multiplied by frequency.

What is the speed of ripples in a pond with a wavelength of 0.08 meters and a frequency of 2 Hertz?

• 0.16 meters per second

• 0.08 meters per second

• 0.04 meters per second

• 0.32 meters per second

If a seismic wave travels at 3,000 meters per second with a frequency of 0.25 Hertz, what is its wavelength?

• 1,200 meters

• 3,000 meters

• 750 meters

• 12,000 meters

What is the frequency of a sound wave traveling at 340 meters per second with a wavelength of 0.2 meters?

• 680 Hertz

• 340 Hertz

• 1,700 Hertz

• 170 Hertz
