The Path of a Ray of Light entering a Glass Slab at an Angle of 45°
When a ray of light enters a glass slab at an angle of 45°, it undergoes several changes in its path. Let's discuss each step in detail:
1. Angle of Incidence:
The angle at which the ray of light enters the glass slab is called the angle of incidence. In this case, the angle of incidence is 45°.
2. Angle of Refraction:
According to Snell's law, the angle of refraction is related to the angle of incidence and the refractive indices of both the media. The refractive index of air is approximately 1, and the refractive index of glass is typically around 1.5. Using the formula, n1 * sin(theta1) = n2 * sin(theta2), we can determine the angle of refraction. In this case, the angle of incidence is 45°, and the refractive indices are 1 (air) and 1.5 (glass). Hence, the angle of refraction can be calculated as sin(theta2) = (1/1.5) * sin(45°).
3. Angle of Emergence:
The angle at which the ray of light emerges from the glass slab is called the angle of emergence. It is related to the angle of refraction and the refractive indices of the media. Since the ray of light emerges in the same medium (air) as it entered, the angle of emergence is equal to the angle of refraction.
4. Lateral Displacement:
The lateral displacement is the horizontal shift of the ray of light after passing through the glass slab. It occurs due to the change in the speed of light as it passes from one medium to another. The lateral displacement can be calculated using the formula, Lateral Displacement = Thickness of the Slab * tan(theta). In this case, the thickness of the glass slab would be given, and the angle theta can be determined using the angle of incidence and the angle of refraction.
Summary:
To summarize, when a ray of light enters a glass slab at an angle of 45°:
- The angle of refraction can be determined using Snell's law.
- The angle of emergence is equal to the angle of refraction.
- The lateral displacement can be calculated using the thickness of the slab and the angle of refraction.
