Question

На какой угол отклонится луч от первоначального направления, если он упал под углом 45 на поверхность стекла(Срочно)

Answer 1

такой же угол 45 градусов

 

Answer 2

$\alpha=45^0\\n_1=1\\n_2=1.6$
От вас требуют найти так называемый угол гамма:
$\gamma=\alpha-\beta\ ;\beta=?$

Угол бета находится по закону преломления света:
$\frac{sin\alpha}{sin\beta}=\frac{n_2}{n_1}=>sin\beta=\frac{sin\alpha}{n_2}=\frac{0.7071}{1.6}=0.4419\\\beta=26^0\\\gamma=45^0-26^0=19^0$

Answer 3

Calculating the Angle of Deviation for Light Passing Through Glass

When light passes through a medium such as glass, it changes direction due to the change in speed. This phenomenon is known as refraction. The angle of deviation can be calculated using the formula:

Angle of Deviation = 2 * (Refractive Index - 1) * Angle of Incidence

Where: - Refractive Index is a measure of how much the speed of light is reduced inside the medium compared to its speed in a vacuum. - Angle of Incidence is the angle at which the light ray strikes the surface of the medium.

In this case, the light ray falls on the surface of the glass at an angle of 45 degrees. To calculate the angle of deviation, we need the refractive index of the glass.

Refractive Index of Glass

The refractive index of glass varies depending on the type of glass. However, for common types of glass, the refractive index is approximately 1.5.

Calculation

Using the given angle of incidence (45 degrees) and the refractive index of glass (1.5), we can calculate the angle of deviation:

Angle of Deviation = 2 * (1.5 - 1) * 45

Angle of Deviation = 2 * 0.5 * 45

Angle of Deviation = 45 degrees

Therefore, the angle of deviation for the light passing through the glass at a 45-degree angle would be 45 degrees.
