In a young's double-slit experiment, the slits are 0.03 cm apart and the screen is placed 1.54 m away. The distance between the central bright fringe and fourth bright fringe is 1 cm. Calculate the wavelength of light used.
Describe Netwon's ring experiment and derive expression for wavelength of light.
If light travels from one medium to another, its velocity changes. Is it due to the change in frequency or wavelength? Explain.
A wire whose mass is 10-3 kg/m is stretched by a load of 4kg over the two bridges of a sonometer wire 1 m apart. It is struck at its middle point. What would be the wavelength and frequency of its fundamental vibration?
A source of the sound of frequency 550 Hz emits waves of wavelength 60 cm in the air at 20° C. What would be the wavelength of sound from the source in the air at 0° C.
A radio station broadcasts at 800 kHz. If the radio waves (em-waves) travel with a speed of 3x10^8 m/s, what will be the wavelength of the wave?
