Explain about the term spatial coherence of Laser.
Spatial coherence:
This coherence is a measure of the correlation among the phases of a light wave at several points’ transverse to the direction of propagation. This coherence tells us how identical the phase of the wave front is. More exactly, the spatial coherence is the cross-correlation in between two points into a wave for all times. When a wave has only one value of amplitude over an infinite length, then this is absolutely spatially coherent.

Laue pattern (M. von Laue): The pattern generated on a photographic film while high-frequency electromagnetic waves (such as x-rays) are fired at a crystalline solid.
An object is thrown at 25 m/s at 39 degrees above the horizontal from a 40m tall cliff. How long is it in the air?
Landauer's principle: A principle that states it doesn't take energy to compute data explicitly, but rather it takes energy to erase any data, as erasure is a significant step

Can you explain coherent sources of light?
why specific heat is different at different temperature?
Q. The half life of radon is 3.8 days. Calculate mean life. Half Life Period HLP T ½ = 0.6931 / λ = 0.6931 τ therefore Mean life τ = T ½ / 0.
