A beam of monochromatic light is diffracted by a slit of width 0.630 mm. The diffraction pattern forms on a wall 1.70 m beyond the slit. The width of the central maximum is 2.10 mm. compute the wavelength of the light.
A mass m orbits around a planet of mass M in a parabolic orbit of the form y = x^2/(4L), which has focal length L. Find the angular momentum in 3 different ways: a) Find the speed at closet approach.
During a mountain climbing trip, it is observed that the water used to cook a meal boils at 90°C rather than the standard 100°C at sea level
a 5.0 g ice cube at -20degree cis in a rigid sealed container from which all the air has been evacuated.how much heat
A light ray enters a rectangular glass slab (n = 1.5) at point A at an incident angle theta, what is the index of refraction of the unknown liquid
Let us understand why the moon has no atmosphere......We need to remember some mechanics here! Taking the temperature of the surface of the moon to be 107 degree C (actually this is the mean day-time temperature), calculate the root mean square sp..
The energy of sunlight hitting the earth is about 1400 W/m^2 (where 1 W= 1 J/s) in mid day. Given that the sun is about 150 million km from the earth, estimate the total output of the sun
Calculate the wavelength of light emitted by a hydrogen atom when an electron makes a transition from n=8 to n=2 levels
Vector A~ has a magnitude of 9 and points in the positive x-direction. Vector B~ has a magnitude of 19 and makes an angle of 38? with the positive x-axis
In a ballistics test, a 23-g bullet travelling horizontally at 1300 m/s goes through a 40.0 cm-thick 450-kg stationary target and emerges with a speed of 900m/s. The target is free to slide on a smooth horizontal surface.
suppose there is significant air resistance in addition to the spring force acting on the mass as it oscillates up and down. how will the elastic potential energy change
calculate the first and second order angles for light of wavelength 675 nm for a diffraction grating contains 8000
