Huygens' construction; Huygens' principle (C. Huygens):
The mechanical propagation of any wave (exclusively, of light) is equal to supposing that each point on the wavefront behaves as point source of wave emission.
Ask queA cart of weight 25 N is released at the top of an inclined plane of length 1m, which makes an angle of 30° with the ground. It rolls down the plane and hits another cart of

Occam's [or Ockham's] razor (William of Occam [or Ockham]; c. 1340): The recommendation that the simpler a theory is, the better. If two of the theories predict phenomena to t
Falling bodies If you can search a building that is about 20 m high in your locality you can examine how gravity makes bodies fall faster the longer it acts on them. Get a piec
Brownian motion (R. Brown; 1827) It is the continuous random motion of solid microscopic particles while suspended in a fluid medium because of the consequence of ongoing bomb
Q. Find the minimum wavelength of X-rays produced by an X-ray tube operating at 1000 kV. λmin = 12400 A 0 / V Therefore λmin = 12400 X 10 -10 / 10 6 = 0.0124 A 0
Vertical Circular Motion A mass is in circular motion within the vertical plane. We show the weight and force exerted through the tension within the string.
What do you mean by Moseley's law? Explain briefly its importance. Explain the origin of X-ray spectra. Describe continuous and characteristic x-ray spectrum.
The process of apparent change in frequency (or wavelength) of the light because of relative motion among the source of light and the observer is known as Doppler's effect.
