Light propagates as transverse EM rays. The magnitude of electric field is much larger as compared to magnitude of magnetic field. We generally prefer to define light as electric field oscillations.
compostion of two simple harmonic motion
What is the stimulated emission? Define this term briefly. Stimulated emission: a. While photon interacts along with atom that is in the excited state E 2 , in that case de-
Determine the zero-point energy of a harmonic oscillator havingof a particle of mass 2.33 x 10 -26 kg and force constant 155 N m -1 .
#questA ball of mass 1.5 kg rolling to the right with a speed of 3.6ms-1, collides head-on with a spring with a spring constant of 2.0Nm-2.Determine the maximum compression of the
An astronomer observes that a molecule in a galaxy travelling toward Earth emits light with a wavelength of 514 nm. The astronomer identifies the molecule as one that actually
What is the means in which light waves travel? Ans: Light is the only type of wave that doesn't require a medium. Confirmation that light will travel through vacuum is the
What is damped and undamped eletromagnetic waves Ans) A damped wave is a wave whose amplitude of oscillation decreases with time, eventually going to zero.
Find the speed of the wave A copper wire, whose cross-sectional area is 1.1 x 10 -6 m 2 has a linear density of 7.0 x 10 -3 kg/m and is sturng between two walls. At the ambient
