The Critical angle of perspex is 42o.
It is the same as the critical angle of glass.
Yes, there is a critical angle for light traveling from glass to water. This critical angle is the angle of incidence that results in light being refracted along the interface between the two mediums, rather than being transmitted into the other medium. The critical angle can be calculated using Snell's Law.
The critical angle of light passing from glass to water is minimum when the light is passing from a denser medium (glass) to a rarer medium (water), which is when the light travels along the normal. At this orientation, the critical angle is the smallest possible value for the glass-water interface.
The critical angle of water is the angle at which light traveling from water to air bends so much that it reflects back into the water instead of refracting out. This phenomenon, known as total internal reflection, occurs when the angle of incidence is greater than the critical angle. It is important in optical devices like fiber optics, where light is transmitted through materials by reflecting off their boundaries.
When a beam of light meets a perspex surface at an angle, it will undergo refraction, which is the bending of light as it passes from one medium to another with a different refractive index. The angle of refraction will depend on the angle of incidence and the refractive indices of the two materials.
The difference in density between the perspex block and the water is what determines whether it sinks or floats. In fresh water, the density of the perspex block is greater than that of the water, causing it to sink. However, in very salty water, the increased density of the water allows the less dense perspex block to float.
Yes, there is a critical angle for light transitioning from glass to water. The critical angle occurs when light moves from a medium with a higher refractive index (glass) to one with a lower refractive index (water). If the angle of incidence exceeds this critical angle, total internal reflection occurs, meaning no light passes into the water. The critical angle can be calculated using Snell's Law.
Because of the difference in the density of the materials.
A critical angle refers to the highest angle the light can possibly refract into or between objects without disappearing. ie = light going from crystal into water, the critical angle is 47degrees.

When a beam of light meets a perspex surface at an angle, it will undergo refraction, which is the bending of light as it passes from one medium to another with a different refractive index. The angle of refraction will depend on the angle of incidence and the refractive indices of the two materials.
The definition of critical angle is the angle of incidence that refraction can still occur.
