A plane electromagnetic wave is incident on a material surface. The wave delivers momentum p and energy E.

As we know, the range of wavelength of visible radiation is from 400 nm to 700 nm. The radiation having wavelength greater than 700 nm is termed as infra-red radiations...

(a) along the electric field

(a) electric field (b) magnetic field

(i) Standard equation of magnetic field is By = B0sin(ωt + kx)T Comparing this equation with the given equation, we get B0 = 8 x 10-6T, ω = 2 x 1011 rad s-1, k...

The angle i and refractive index μ = tani

Electric field vector along X-axis Magnetic field vector along Y-axis.

Electric field along Y-direction. Magnetic field along Z direction. (so that vector K, vector E, vector B form a right handed system) 

Electric field along X-direction. Magnetic field along Z-direction

The frequency of electromagnetic waves does not change while travelling through a medium.

(d) Hepatic portal vein deliver the nutrient rich blood from the stomach and small intestine to the liver. It is the largest gland in the body.
