A ray of light falls on a glass slab of refractive index u.if the reflected and refracted rays are mutually perpendicular to each other,find the angle of incidence.
Ans) let i be angle of incidence then angle of reflection is i ,by snell law sin i=usin r90-i+90-r=90i+r=90putting in above eqn.u= tan i
why the light vibrating in the plane ofincidence is not reflected at Brewster''s angle?
N-Type Substances: When a small quantity of Arsenic or Phosphorous (group VA elements) is added to silicon or Germanium, it becomes good conductor of negative charges, such a s
In mechanics, stress is a measure of the internal forces acting within a deformable body. Quantitatively, it is a measure of the average force per unit area of a surface within the

IONIC BOND Ionic bonding involves the transfer of electrons from an electropositive atom (an atom that tends to "donate" an electron) to an electronegative atom (an atom that t
There are two major differences between "center of gravity" and "center of mass": 1) The term "center of gravity" aplies to the bodies with mass and weight, while the term "cent
The measurements taken in Ramdesns eyepiece more worthy (reliable) than Huygens eyepiece. Why? Describe critical angle. show its relationship with refractive index.
It is the distance travelled by the disturbance in single time period. It only relays on the properties of the medium and it independent of time and position.
Where is the electric potential because of a single negatively charged particle a maximum? Answer: One could acquire at this one by looking at the formula for the electri
