For a resonance tube apparatus with a total tube length of 1m, how many
resonance positions would be observed when the water level is lowered
through the total length of the tube for a tuning fork with a frequency of
(a) 500 Hz, (b) 1000 Hz? (Velocity of sound in air = 347 ms-1).

Explanation:
I assume that the tube is open at one end. What is the condition for resonance for a half-open tube? What variables figure into that condition? For which of those variables do you have actual values? How would you relate the variables to the given values, frequencies?
