Electromagnetic radiations:
What are the common features among all the Electromagnetic radiations?
Ans: 1. They all can be described in terms of oscillating electric and magnetic fields perpendicular to each other.
2. They are transverse in nature.
3. All the radiations travel with the speed of light
The equation of reflected wave for soft boundary: y(x.t)=A cos[(wt-kx)] The equation of reflected wave for rigid boundary: y(x.t)=A cos[(wt+kx)] where A=amplitude of the wave
A scalar function is given by f(x, y, z) = 2xy 2 + xyz 3 . Calculate the gradient of the function at the point (1, 1, 1).
Component Addition of vector We learned in which vectors oriented at right angles to one another could be added together by using the Pythagorean Theorem. For example, two disp
