Question

Угол падения луча света равен 30градусов.Начертите падающий и отражанный лучи.Обозначьте углы падения и отражения.Чему равен угол отражения? чему равен угол между падающим и отражёнными лучами?

Answer 1

Угол отражения равен углу падения, т. е. 30 градусов
угол между ними =30+30=60

Answer 2

угол отражения=углу падения=30 градусов

угол между падающим и отражённым лучами = (90-30)*2=120 градусов

Answer 3

Angle of Incidence and Reflection

When a light ray strikes a surface, it can be reflected, absorbed, or transmitted. In this case, the angle of incidence is given as 30 degrees. Let's discuss the angles of incidence and reflection and draw the incident and reflected rays.

The angle of incidence is the angle between the incident ray and the normal to the surface at the point of incidence. The normal is a line perpendicular to the surface. In this case, the angle of incidence is 30 degrees.

The angle of reflection is the angle between the reflected ray and the normal to the surface at the point of incidence. According to the law of reflection, the angle of reflection is equal to the angle of incidence. Therefore, the angle of reflection is also 30 degrees.

To visualize this, let's draw the incident and reflected rays:

      \   |   /
       \  |  /
        \ | /
         \|/
          \
          /|
         / |
        /  |

In the diagram above, the incident ray is represented by the line coming from the left side and striking the surface at an angle of 30 degrees. The reflected ray is represented by the line coming from the right side and leaving the surface at an angle of 30 degrees as well.

The angle between the incident and reflected rays is the angle of reflection. In this case, the angle of reflection is 30 degrees.

Please note that the diagram is a simplified representation and does not take into account other factors such as refraction or the specific properties of the surface.
