Bragg's law (Sir W.L. Bragg; 1912)
While a beam of x-rays strikes at crystal surface wherein the layers of atoms or ions are separated regularly, the maximum intensity of the reflected ray takes place while the complement of the angle of incidence, theta, the wavelength of x-rays, lambda, and the distance among layers of atoms or ions, d, are associated by the equation
2 d sin theta = n lambda,
Where n is an integer.
Light is normally incident on a thin soap film and is reflected. If the wavelength of this light is "L" and the index of refraction of the soap film is "N", complete destructive i
Define the Cylinders and Heat Bath? Regard as a cylinder 1 m long with a thin, massless piston clamped in such a manner that it divides the cylinder into two equal parts. The
A body moves along x-axis with velocity v at position x. If the plot v-x is an ellipse with major axis 2A and minor axis 2u, what is the modulus of maximum acceleration?
what is elastic fatigue
explain the construction and working of compound microscope

a) Heat produced or absorbed at a junction is proportional to the current by the junction. b) This effect is produced when current is passed by junction of suitable materials.
I think it is same as the apex angle of the prism or the angle of the prism. since it decides the angle of deviation as i+e=D+A(angle of the prism),D=deviation.

the average speed of an object over a given time duration is 6 m/s. If it travels first half of the duration with a constant speed 4 m/s, its speed during the next half duration is
