Rotating a Mirror and the Reflected Ray
Describing in which when a mirror is rotated through an angle, the reflected ray is rotated through twice that angle. You might drag the slider in the animation at left side top, to rotate the mirror.
A hydrogen atom is in the ground state. It absorbs energy and makes a transition to the n = 3excited state. The atom returns to the ground state by emitting two photons. What are
A bar has a 20N weight at one end. You have a weight of 15N to hang somewhere on the bar so that the bar is in equilibrium. Where would you hang the 15 N weight on each of these ba
Q. The kinetic energy of an electron 120 eV. Compute the de Broglie wavelength of electron. λ = h / √2mE λ = 6.626 X 10 -34 / √ 2 X 9.1 X 10 -31 X 120 X 1.6 X 10 -19
If the angle of incidence is 60 degrees,then what is the angle of deviation?
what are electromagnetids
A ram-air intake is any intake design which uses the dynamic air pressure produced by vehicle motion to increase the static air pressure inside of the intake manifold on an engine,
Phase (Φ) : The amount which express at any instant, the displacement of the particle and it's direction of motion is known as the phase of the particle. If two elements of the
Materials which can be magnetized are called magnetic materials. When magnetized, such materials create a magnetic field around them. Some of the significant features of magnetic m
Consider an electron in a simple one-dimensional periodic potential. The energy of the electron will vary periodically due to the influence of the periodic potential, and can be de
The effects of back emf on circuit current: In proving the time constant, it was stated that, at the instant the switch is closed, the current (I) is zero. This is because, at
