SOUND (PART2) CLASS 8 | CHARACTERISTIC OF SOUND

Fig. shows wave patterns of three sounds A, B and C. Name the characteristic of sound which is the same between (i) A and B, (ii) B and C, and (iii) C and A.

At the room temperature the velocity of sound in O_(2) gas is v. Then in mixture of H_(2) and O_(2) gas the speed of sound at same temperature :-

Note is a sound :

A gas is a mixture of two parts by volume of hyprogen and part by volume of nitrogen at STP . If the velocity of sound in hydrogen at 0^(@) C is 1300 m//s . Find the velocity of sound in the gaseous mixure at 27^(@)C .

The characteristics of sound with the help of which we can distinguish between a SHRILL note and a GRAVE note is

The velocity of sound in hydrogen at STP is 1400ms^(-1) . Find the velocity of sound in a mixture with 3 parts by volume of oxygen and 2 parts by volume of hydrogen at 819^(@)C ?

The velocity of sound in hydrogen at 0^@C" is 1.28kms"^(-1) . Calculate the velocity of sound in a mixture of 4 parts by volume of hydrogen and one part of oxygen at the same temperature?

A sound differs by 6 dB from a sound of intensity equal to 10(nW)/(cm^2) . Find the absolute value of intensity of the sound.

A sound differs by 6 dB from a sound of intensity equal to 10(nW)/(cm^2) . Find the absolute value of intensity of the sound.

It takes 2.0 seconds for a sound wave to travel between two fixed points when the day temperature is 10^(@) C . If the temperature rise to 30 ^(@)C the sound wave travels between the same fixed parts in
