Part 1 of question: Consider the case when light passes from one medium into another medium that has a lower index of refraction, for instance, from glass to water. Is there an angle of incidence for which the refracted angle is 90 degrees? If there is, derive an expression for this angel in terms of the two indicies of refraction.
Part 2 of question: will there be any refraction of light waves if the metal slit is placed on the rear glass plate directly behind the ethced line on the front plate?
The tire on a bicycle is filled with air to a gauge pressure of 691 kPa at 20?C. What is the gauge pressure in the tire after a ride on a hot day when the tire air temperature is 48?C?
The weight of your 1205-kg car is supported equally by its four tires, What gauge pressure is required to give an area of contact of 112 cm2 for each tire
A mass spectrometer has an adjustable magnetic field. When themagnetic field is 7.000e-2 T, a singly ionized hydrogen atom (a proton) will strike the detector at a particular location. Suppose a triply-ionized carbon 12 atom, whose mass is by defi..
On the basis of the Bohr model consider the doubly ionized Li atom: If an electron in this atom makes a transition from n=2 to the ground state, discover the energy, momentum and wavelength of the emitted photon.
Two crates, of mass 77 kg and 108 kg, arein contact and at rest on a horizontal surface (Fig. 4-47). A 729 Nforce is exerted on the 77 kg crate.If the coefficient of kineticfriction is 0.15, calculate the following: the force that eachcrate exerts..
