A vibrating tuning fork is moving slowly and uniformly ins a horizontal circular path of radiu 8 m . The shortest distance of an observer ins ame plane from the tuning fork is 9m. The distance between the tuning fork and observer at the instant when apparent frequency becomes maximum is

There is a source of sound (a tuning fork) moving towards a reflecting wall will a speed of 30 ms^(-1) . The velocity of the sound in air is 330 ms^(-1) and the frequency of the tuning fork is 600 Hz. The observer is between the source and the wall and is moving with some velocity V_(1) towards the wall. The beat frequency heard by the observer is 4 Hz. If the tuning fork is waxed, the frequency beats heard by the observer becomes 3 Hz. If the new frequency of tuning fork is k then k//50 is

The frequency of a tuning fork is 220 Hz and the velocity of sound in air is 330 m/s. When the tuning fork completes 80 vibrations, the distance travelled by the wave is

A vibrating tuning fork tied to the end of a string 1.988 m long is whirled round a circle. If it makes two revolutions in a second, calculate the ratio of the frequencies of the highest and the lowest notes heard by an observer situated in the plane of the tuning fork. Valocity of sound is 350 m/s.
