if angle of incidence is 40 degree and angle of refraction is 30° and refracted Ray is devuated by
Answers
Explanation:
angle of incidence is equal to the angle of refraction. In a glass slab, if angle of incidence is 30 degree........then the angle of refraction should be lesser than that, right ??? Coz......the ray bends towards the normal when it enters into the denser medium !!!!!
Answer:
The refracted ray is deviated by 10°.
Explanation:
When a light ray is incident upon a medium, it is refracted or bent from its original path. The angle of incidence is the angle between the incident light ray and the normal to the surface at the point of incidence. The angle of refraction is the angle between the refracted light ray and the normal to the surface at the point of incidence. In this case, the angle of incidence is 40° and the angle of refraction is 30°.
In order to calculate the angle of deviation, we can use the formula δ= i-r, where δ is the angle of deviation, i is the angle of incidence and r is the angle of refraction. Using this formula, the angle of deviation is 10° (40°-30°).
The angle of deviation, δ, is the angle between the incident and refracted rays and can be calculated using the law of refraction which states:
δ = θi - θr
The angle of deviation (Δ) is calculated using the equation Δ = θi - θr, where θi is the angle of incidence and θr is the angle of refraction.
For this particular problem, δ = 40° - 30° = 10°.
This means that the refracted ray is deviated by 10° from its original path.
When a light ray is refracted, the light ray bends towards the normal. This means that the angle of deviation is measured in the clockwise direction. So, in this case, the refracted ray is deviated in a clockwise direction by 10°. This can also be visualised by drawing a diagram of the incident and refracted rays.
