A tuning fork A, marked 512 Hz, produces 5 beats per second, where sounded with another unmarked tuning fork B. If B is loaded with wax the number of beats is again 5 per second. What is the frequency of the tuning fork B when not loaded?

This is a short answer type question as classified in NCERT Exemplar
Frequency of tuning fork A
Hz
Probable frequency of tuning fork B
Hz or 507Hz
When B is loaded its frequency reduces .
If it is 517Hz it might reduced to 507Hz given again a beat of 5Hz
If it 507Hz reduction will always increase the beat frequency, hence Hz

The acceleration of wave is g/2. Its speed increases as it moves up. So answer is (2)
Distance between successive compression and rarefaction is λ/2
.
Both points B and G are moving up and are at same distance from equilibrium position at the instant.
Equation of component waves are
y = Asin (ωt – kx) and y = Asin (ωt + kx)
So speed of component wave is (ω/k).
