Methods for Measuring Wave Speed

The video tutorial explains methods to measure wave speed using two equations: V = X/T and V = Lambda*F. It provides examples of calculating the speed of sound in air using echoes and the speed of surface water waves by measuring the time taken to travel between two points. The tutorial emphasizes understanding the relationship between distance, time, and wave speed, and demonstrates calculations with practical examples.

Which of the following equations can be used to calculate the speed of a wave?

• V = X * T

• V = X / T

• V = F / Lambda

• V = Lambda / F

In the example of calculating the speed of sound in air, what is the total distance the sound wave travels?

• 85 meters

• 340 meters

• 0.5 meters

• 170 meters

What is the calculated speed of sound in air from the given example?

• 85 meters per second

• 170 meters per second

• 340 meters per second

• 680 meters per second

In the water wave example, what is the distance between the two poles?

• 100 meters

• 50 meters

• 25 meters

• 75 meters

What is the speed of the surface water waves calculated in the example?

• 1.25 meters per second

• 2.5 meters per second

• 5 meters per second

• 0.5 meters per second
