Angle Between Two Plane

Angle between two lines

Angle Between Two Vectors

The angle q between two plane mirrors producing five images of a given object is given by.

Angle between 2 planes || Angle between a plane & a line || Distance OF a point from plane & normal form OF plane

An object is placed between two plane mirrors inclined at an angle to each other. If the number of images formed is 7 then the angle of inclination is -

Assertion : If theta is the angle between the planes of transmission of two analysers then the intensity of emergent light is proportional to cos^@ theta . Reason : In the propagation of electromagnetic waves, the angle between the direction of propogation and plane of polarisation is pi/2 .

In the propagation of polarised light waves, the angle between the plane of vibration and the plane of polarization is

In a plane polarised electromagnetic wave, the angle between the planes of bivration and polarisation is
