Calculate Velocity of a Wave

Select the correct equations.

• Speed = distance / time

• Distance = speed x time

• Distance = speed / time

• Time = distance / speed

• Speed = distance x time

Select the correct equations.

• Speed = frequency / wavelength

• Wavelength = speed / frequency

• Speed = frequency x wavelength

• Frequency = speed x wavelength

• Frequency = speed / wavelength

A firework is fired straight upwards. It explodes 272 m above the ground. It takes the sound wave from the firework 0.8 s to reach the ground. Calculate the speed of sound in air.

A paddle vibrating up and down in a pool is used to produce waves on the water. The wavelength of each wave is 1.2 m and exactly 2 complete waves are produced per second. Calculate the speed of the wave.

A water wave is generated by a wave machine in a pool. The wave travels to the end of the pool, is reflected, and travels back to the wave machine. It takes 8.0 seconds for the wave to return to the machine once it has been generated. The wave travels at a speed of 4.5 m/s. How far from the end of the pool is the wave machine?
