EASY
A calcite crystal is placed over a dot on a piece of paper and rotated. On seeing through the calcite, one will see
EASY
A wave of frequency =3 GHz, strikes a particle of size 1100th of λ, then this phenomenon is called as
MEDIUM
A ray of light travelling in impure water is incident on a glass plate immersed in it. When the angle of incidence is 51°, the reflected ray is totally plane polarized. Given that refractive index of impure water is 1.4. The refractive index of glass should be _____ tan51°=1.235
EASY
If the light is polarized by reflection, then the angle between reflected and refracted light is
EASY
In a stạck of three polarising sheets, the first and the third are crossed while the middle one has its axis at 45° to the axes of the other two. The fraction of intensity of an incident unpolarised beam of light that is transmitted by the stack is
MEDIUM
The Brewster's angle for air to water interface is
MEDIUM
A beam of plane polarized light of large cross-sectional area and uniform intensity of 3.3 W m2 falls normally on a polarizer (cross-sectional area 3×104 m2), which rotates about its axis with an angular speed of 31.4 rad s-1. The energy of light passing through the polarizer per revolution, is close to:
EASY
When the angle of incidence on a transparent material is 60°, the reflected light is completely polarised. The velocity of refracted ray inside the material is
EASY
When an unpolarized light of intensity I0 is incident on a polarizing sheet, the intensity of light which does not get transmitted is
EASY
Unpolarized light of intensity I passes through an ideal polariser A. Another identical polariser B is placed behind A. The intensity of light beyond B is found to be I2. Now another identical polariser C is placed between A and B. The intensity beyond B is now found to be I8 . The angle between polariser A and C is
EASY
