Question

Умные физики,помогите,пожалуйста <3 Физика!Луч падает под углом 30* на границу раздела воздух-стекло. Чему равен угол преломления. Абсолютный показатель преломления стекла 1,5

Answer 1

Угол падения а=30°

sin30/sinb=1,5

sinb=1/2:(3/2)=1/3

b=arcsin(1/3).

b - угол бета, угол преломления.

Answer 2

Calculation of the Angle of Refraction

To calculate the angle of refraction when a light ray passes from one medium to another, we can use Snell's law. Snell's law states that the ratio of the sine of the angle of incidence to the sine of the angle of refraction is equal to the ratio of the velocities of light in the two media.

Mathematically, Snell's law can be expressed as:

n₁ * sin(θ₁) = n₂ * sin(θ₂)

Where: - n₁ is the refractive index of the first medium (in this case, air or vacuum) - θ₁ is the angle of incidence - n₂ is the refractive index of the second medium (in this case, glass) - θ₂ is the angle of refraction

In this case, the angle of incidence (θ₁) is given as 30 degrees, and the refractive index of glass (n₂) is given as 1.5.

To find the angle of refraction (θ₂), we can rearrange Snell's law as follows:

sin(θ₂) = (n₁ / n₂) * sin(θ₁)

Substituting the given values, we have:

sin(θ₂) = (1 / 1.5) * sin(30°)

Using a calculator, we can evaluate this expression to find the value of sin(θ₂).
