In the thin lens equation first prove that Zz = f*f (Hint use this diagram along with the characteristics of similar triangles). Then use this equation along with the act that Z^ = Z + f, z^ = z + f to prove the thin lens equation, which is equation 2.2 in the book. What are the two values of z^ for the cases where Z^ is plus infinity, and where Z^ = f.
Figure shows the frequency spectrum of a signal at 1184kHz displayed by a high-speed virtual DSO. Determine (a) The harmonic relationship among the signals marked 'o' and 'x',
UV radiations and X - rays are: UV radiations are produced by the high energy transitions of the electrons in atoms. UV radiations have wavelengths ranging from 0.4 m m to 1n
Physical arrangement of resistors: Before we look at some problems it is necessary to warn you that physical appearances can be deceptive. When components are mounted they are
In the figure below the closed curves A and B represent closed surfaces. What is the total flux by the closed surface A? Ans: In concurrence with Gauss's Law the net o
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.
Kinematics of Projectile Motion One of the powers of physics is its capability to use physics principles to form predictions about the final outcome of a moving object. Such pr
