UrbanXrisis said:is it possible to focus an axial ray through a double plano piece of glass placed in air?
i don't think so because the glass will not reflect the ray towards the optical axis for the ray to focus in. is this thinking correct?
A focus axial ray is a type of light ray that is emitted from a point and travels in a straight line until it reaches a focus point. It is commonly used in optics and is a fundamental concept in physics.
Yes, a focus axial ray can pass through glass. Glass is a transparent material, meaning that light can pass through it. As long as the angle of incidence of the ray is less than the critical angle, the ray will pass through the glass without being reflected or refracted.
The direction of a focus axial ray may be slightly altered as it passes through glass due to refraction. This means that the ray will change direction and continue to travel in a straight line, but at a different angle. The amount of refraction depends on the properties of the glass, such as its refractive index.
Yes, a focus axial ray can pass through other transparent materials besides glass, such as water or air. However, the amount of refraction may vary depending on the material's properties, such as its density and refractive index.
The ability of a focus axial ray to pass through glass is significant in various fields, including optics, astronomy, and photography. It allows us to use lenses and prisms to manipulate and focus light for various purposes, such as creating images or studying the properties of light.
