A beam of unpolarized light in air strikes a flat piece of glass at an angle of incidence of 54.2 degrees. If the reflected beam
Stels [109]

Answer:

correct option is B. 1.39

Explanation:

given data

angle of incidence (θ) = 54.2 degrees

to find out

index of refraction of the glass

solution

we know that here reflected beam is completely polarized

so angle of incidence = angle of polarized    ....................1

for reflective index we apply here Brewster law that is

μ = tan(θ)     ...............2

put here θ value we get

μ = tan(54.2)

μ = 1.386

so correct option is B. 1.39

1.A graduated cylinder with a least count of = 0.5 ml is used in a density
Anna007 [38]

We have that

 

From the question we are told

  • A graduated cylinder with a least count of \pm 0.5 ml
  • The initial water level, before inserting the irregular
  • shaped solid.
  • Is 30.0 ml. After inserting the solid,
  • The water level is 34.5 ml.

Generally the equation for the new quantity. is mathematically given as

X=Initial level - Final Level \pm (initial and final error)

Therefore

X (34.5-30.0) \pm(0.5+0.5)\\\\X= 4.5\pm 1.0

Therefore

The Probable error is

x=\pm 1.0ml
