Working of Compound Microscope:
The object under examination is placed in front of the objective. The objective forms it's real and inverted image with in the focal length of the eye piece. The eye piece acts as magnifying glass and the final image is virtual and magnified many times.
Fizeau method (A. Fizeau, 1851): One of the first really relativistic experiments intended to calculate the speed of light. Light is flow through a spinning cogwheel driven th
Generate and plot a sampled sine wave with fs=8kHz, of 4 seconds duration, with frequency ?0 = ?/10 and amplitude A = 1.2. The waveform equation is x(n) = A sin n?
