Properties of laser:
Lasers have applications in various disciplines of science and technology. They also find applications in industry, medicine and defence and space science.
Important laser characteristic property "temporal coherence" Due to directionality even laser light travel up to 1km its spreads below 1cm diameter only. Due to high intensity 1volt laser is equal to 1000w ordinary bulb.
For each element the number of neutrons in the nucleus can vary. Isotopes :Nuclei of given element with different numbers of neutrons.If they are not radioactive they called

My question is that if voltage is increased, the electrons will move faster and the distance between them is changed. Why?
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
Determne the magnetic field due to a finit sraight wire of length 2l, carrying a steady current i. The point of interest P is l distance away from the middle point of wire O. So
Eye Chamber: The ball is separated into two chamber, the aqueous chamber and the vitreous chamber. Working: Parallel rays from an object converged by the eye lens and b
SPEED: The distance covered by a body in unit time is known as speed. It is represented by V.
Q. Why does the sky appear blue in colour? As-per to the Rayleigh's scattering law the shorter wavelengths are scattered much more than the longer wavelengths. The blue look o
