Draw graph for a wave representing wave disturbances and time for a sound changing from low pitch to high pitch, keeping amplitude of the sounds same.

How are wavelength, speed and time period related for a sound wave?

What are wavelength, frequency, time period and amplitude of a sound wave?

Answer the following questions: Two students are separated by a 7 m partition wall in a room 10 m high. If both light and sound waves can bend around obstacles, how is it that the students are unable to see each. other even though they can converse easily.

Sound wave from a point source are propagating in all directions. What will be ratio of amplitudes at distances of 9 m and 25 m from the source?

A sound wave creates oscillation in air at a place 1000 times in 100 secons. Find the time period and frequency.
