Two slits 0.45 mm apart are placed 75 cm from a screen. What is the distance between the second and the third dark lines of the interference pattern on the screen when the slits are illuminated with monochromatic light of the wavelength 500 nm?
In Young's double-slit experiment, how is the fringe width altered if the separation between the slits is doubled and the distance between the slits and the screen is halved?
A source of sound generates sound waves that travel with a speed of 340 m/s. The frequency of the source is 500 Hz. Find the frequency of the sound heard if:
When a jet plane is flying at an elevation of 1000 m the sound level on the ground is 4.0 dB. What would be the intensity level on the ground when its elevation is as low as 50 m?
Two notes, one produced by violin and the other by sitar, may have the same frequency, yet we can distinguish between them. Why?
Which has a more direct influence on the loudness of a sound wave: the displacement amplitude or the pressure amplitude? Explain your reasoning.
A piano string 1.5 m long is made of steel of density 7800 kg/m^3 and young's modulus 2x10^-11 N/m^2. It is maintained at a tension that produced an elastic strain of 1% in the string. Calculate the frequency of transverse vibration of the string when it is vibrating in the second mode of vibration.
What is mean by resonance? Explain in detail how you would use sonometer to determine the frequency of a given tuning fork.
