In a Young's interference experimental arrangement, the incident yellow light is composed of twpo wavelength 5890Å. The distance between of the two slits is 10^(-3)m and screen is placed 1m away. Upto what order can frings be seen on the screen and how far from the centre of the screen does this occur?

In standard Young's double-slit experiment, 9 fringes are found to be formed in a portion of screen. Wavelength of light used is 600 nm. How many fringes will be formed in the same portion of screen if wavelength of light is changed to 450 nm?

A bar magnet is put on the hanger of oscillation magnetometer and is made to oscillate in earth's magnetic field. Frequency of oscillation of bar magnet is found to be 3 Hz at a place where horizontal component of earth's magnetic field is 25 muT . Now a short magnet is placed to the north of magnetometer in such a manner that its North Pole points towards north. Distance of short magnet from the bar magnet hanging inside the magnetometer is 1 m. Frequency of oscillation now becomes 6 Hz. What is magnetic moment of short magnet?
