VELOCITY OF A WAVE

A person is watching the passing of the waves on the shore of a beach. Count 100 waves in one minute. If the crest of a wave travels at a speed of 15 meters per second, what is the wavelength of these waves?

What is the velocity of a wave?

• The velocity of a wave is the length of the wave.

• The velocity of a wave is the distance the wave travels in a given time.

• The velocity of a wave is the temperature at which the wave propagates.

• The velocity of a wave is the amount of sound the wave produces.

A string, with a linear density of 0.006 kg/m, is under a tension of 180 N. What is the frequency necessary for the string to vibrate with a wavelength of 25 cm?

A rope 2.5 meters long is subjected to a tension of 150 N and maintains a transverse wave speed of 250 m/s. What is the mass of the rope?

A researcher is studying waves in a pond and notices that 120 waves pass a specific point in one minute. If the crest speed of a wave is 18 meters per second, what is the wavelength of these waves?

A surfer is in the ocean and watches 90 waves pass a point in the water in one minute. If the crest speed of a wave is 10 meters per second, what is the wavelength of these waves?

A rope 5 meters long is subjected to a tension of 300 N and maintains a transverse wave speed of 200 m/s. What is the mass of the rope?

A string, with a linear density of 0.01 kg/m, is under a tension of 250 N. What is the frequency required for the string to vibrate with a wavelength of 15 cm?
