Doppler effect (C.J. Doppler)
Waves emitted through a moving object as attained by an observer will be blueshifted (compressed) if approaching, redshifted (elongated) if receding. It takes place both in sound with electromagnetic phenomena, though it takes on different forms in each.
A small air bubble is placed 0.04 m inside a glass sphere of refractive index 1.5. When viewed normally from outside it is seen at a depth of 0.03 m. Determine the radius of curvat
Capacitance: If we increase the voltage between the plates, the charge increases, but the ratio of charge to voltage remains the same. This ratio gives the capacitance (C) of
tell the fixed transistor bias and describe the design
This is due to the surface tension of water. Because of the surface tension , the drop tends to have minimum possible surface area, and the shape which is possible with minimum su
Define the Newton's Law of Cooling Newton's Law of Cooling: A cup of hot chocolate has cooled from 92°C to 50°C after 12 min in a room at 22°C. a) What is the value for k (
State of Motion: Inertia is the tendency of an object to resist alters in its state of motion. State of motion of an object is described by its velocity - speed with a direc
For a blackbody, the frequency at which maximum energy is emitted is 3 x 10 13 Hz: A. Give a wavenumber for the wavelength of the infrared emission? B. What is the tempe
Q. If 6.25 X 10 18 electrons flow through a given cross-section in unit time, find the current. Solution: Current I = q / t = ne / t = (6.25 X 10 18X 1.6 X 10 -19) / 1 = 1 A
Illustrate the principle of potentiometer. Define a mathematical experiment for the comparison of emf's of two cells. Define the principle and construction of potentiometer and
The current/voltage relationship for two resistors A and B is as shown in Figure. Verify the value of the resistance of every resistor.
