Light strikes a 5.0-cm thick sheet of glass at an angle of incidence in air of 50°. The sheet has parallel faces and the glass h

xxMikexx [17]

Answer:

30.81°

Explanation:

θ₁ = angle of incidence = 50°

θ₂ = Angle of refraction

n₂ = Refractive index of glass = 1.5

n₁ = Refractive index of air = 1.0003

From Snell's Law

Using Snell's law as:

$n_1\times {sin\theta_1}={n_2}\times{sin\theta_2}$

$1.0003\times {sin50}={1.50}\times{sin\theta_2}$

Angle of refraction= sin⁻¹ 0.5122 = 30.81°.

Orange light of wavelength 0.61 µ m in air enters a block of glass with εr = 1.44. What color would it appear to a sensor embedd

77julia77 [94]

Answer:

$0.5083\ \mu m$

Explanation:

$\lambda_0$ = Actual wavelength = $0.61\ \mu m$

$\varepsilon_r$ = Relative permittivity = 1.44

The observed wavelength in the glass is given by

$\lambda=\dfrac{\lambda_0}{\sqrt{\varepsilon_r}}\\\Rightarrow \lambda=\dfrac{0.61}{\sqrt{1.44}}\\\Rightarrow \lambda=0.5083\ \mu m$

The wavelength lies in the range of green light.

Hence, the observed color of light is $0.5083\ \mu m$

How can you tell if one object has more mass than another does, on a planet without gravity

Serhud [2]

an object is more dense if there is more weight in the same area, its because of the amount of particles and the weight of the particles. eg, 1cm cubed of gold would weigh alot more than 1cm cubed polystyrene, so gold is more dense
