Q1:two steel wires of the same length and stretched by the same force vibrate with frequencies of 440hz and 660 hz respectively.calculate ratios of diameter of wires.
Q2:a well with vertical wall resonate with a note of frequency 7.0hz and doesnot resonate lower frequencies.estimate the depth of the well if the speed of sound in air is 350m/s
Q:3 the water level in vertical glass tube of length 1.0 m can be adjusted a tuning fork of frequency is held at upper open end of the tube.at what position of water level will resonance occur(speed of sound=330m/s.
i am writing answers of these questions
Q1:3/2
Q2:12.5m
Q3:0.125,0.375.0.625,0.875 from top
plz explain ur answers,and explain resonace tube as well

resonance tube...
in a closed pipe, (the water filled tube can be considered a closed pipe...the water is the adjustable end) when waves enter, and hit the end, it will be reflected back....
it will resonate when the part of your wave (node) will hit the end (barrier) and be reflected back and so you hear the intense sound.... if it is not a node like an antinode, it will not resonate.. you will not hear an intense sound.. all you hear is the sound from the tuning fork....
the nice thing about resonance tube is the varrying of the length of your closed tube.... and be able to find the length at which sound resonates at a certain frequency.....
