A wave<span> in a medium in which each point on the axis of the wave has an associated constant </span>amplitude<span>. The locations at which the amplitude is minimum are called </span>nodes<span>, and the locations where the amplitude is maximum are called </span>antinodes<span>. (most of these aren't my own words but I tried to put some in my own words) :)</span>
Polarized light waves are those that have only one plane of vibration. Polarization is the process by which non-polarized light is converted into polarised light. There are numerous ways to polarise light.
A characteristic of transverse waves called polarisation identifies the geometric angle of the oscillations. A transverse wave's oscillation direction is perpendicular to the wave's motion direction.
given
Only 72.0% of the light's intensity makes it through the sheet and hits another sheet of polarising material. The second sheet lets no light flow through it.
Given that no light passes through the second sheet because both sheets are crossed, the angle the transmission axis of the second sheet makes with the vertical is
θ₂ = θ₁ + 90°
= 31.94° + 90°
= 1 21.94°
for the first sheet and
Icos²θ₁ = I
I/I₀ = 0.72
θ₁ = cos⁻¹√(0.72)
= 31.94°
for the second sheet, respectively. This is because the malus law states that I = Iocos²θ₁ for the first sheet.

Answer:
(d) 16°
Explanation:
Using Snell's law as:
Where,
is the angle of incidence ( 25.0° )
is the angle of refraction ( ? )
is the refractive index of the refraction medium (glass, n=1.5)
is the refractive index of the incidence medium (air, n=1)
Hence,
Angle of refraction = 
= 16°
