The critical angle of a certain plastic in air is 37.3 degrees. Wats the critical angle of the same plastic if its immersed in water?
Homework Equations
n1sin( theta)= n2sin(theta)
The Attempt at a Solution
Nair= 1.00
1.00sin37.3/1.33 = sin(theta)
sin(theta)= .455
inverse sin (theta) = 27.1 degrees
Is that right?
Snell's Law is a fundamental principle in optics that describes the relationship between the angle of incidence and angle of refraction when light passes through different mediums.
The equation for Snell's Law is n1sinθ1 = n2sinθ2, where n1 and n2 are the refractive indices of the two mediums and θ1 and θ2 are the angles of incidence and refraction, respectively.
The critical angle is the angle of incidence at which light passing through a medium is refracted at an angle of 90 degrees, resulting in total internal reflection.
The critical angle is affected by the refractive indices of the two mediums and the angle of incidence. It is also dependent on the wavelength of light and the surface characteristics of the mediums.
Snell's Law and critical angle are used in various applications such as optics, telecommunications, and medical imaging. They are also used in the design of lenses, optical fibers, and prisms. In everyday life, we encounter these principles in cameras, eyeglasses, and binoculars.
