If the Glass Block acts as a Prism, then when you shine white light on a it, the White Light refracts into all Primary Colors. When the Light exits the Prism you can see all the rainbow colors.
Some of the light is reflected off the glass at the same angle - in a manner and angle similar to that of a ball deflected off a surface at a similar angle. This is what happens when light reflects from car windows into our faces. Much of the light, however, will penetrate the glass, so that the light source is seen from the other side. Nevertheless, on contact with the glass, the light that penetrates will be refracted (bent) and travel through the glass at a different angle from that of its original contact with the glass; but once having travelled through the glass, it will leave at its original angle of contact. The amount of refraction depends on a number of factors, but especially, on the thickness of the glass and specific angle of contact involved. So, the light bends as it passes through the glass, but leaves at its original angle.
when a ray box is shown at a mirror it reflectes
There is insufficient information for us to even begin to understand this question. Please edit the question to include more context or relevant information. When it hits the glass, light does several things. Some of it is reflected. Some of it is absorbed as it travels through the glass and the rest of it is transmitted through the glass. Light that strikes the glasses at anything other than right angles is also refracted - its path is bent.
If the light is entering from air or a vacuum, the light will slow down. The affect of this, if the light hits the glass at an angle, is that the direction of the light will change.
Hey! The reason it seems to disappear is because of the refraction and absorption of light and colour. When light enters the colourless liquid, colour is obviously absorbed. The light waves refract ("bounce") off the glass test tube and leave the glass beaker (containing the colourless liquid). Because the liquid and solid are the same colour, it creates the illusion of the test tube disappearing.
No, a light ray does not bend if it enters a glass block perpendicularly.
When a ray of light enters a glass block at 90 degrees, it continues in a straight line without bending. This is because there is no change in the speed of light when it enters the glass block at a perpendicular angle.
When light passes through a glass block, it undergoes refraction, which is the bending of light as it enters the glass and again as it exits. The speed of light changes as it moves from air to glass, causing the light rays to change direction.
When light enters a glass block, it changes speed and bends due to refraction, causing the light beam to deviate from its original path. The light exits the glass block at a different angle than it entered. This phenomenon is a result of the change in the speed of light as it passes from air into the denser medium of the glass.
The light ray changes direction as it enters the glass block due to refraction, where the speed of light changes as it passes from one medium to another. This change in direction is caused by the bending of the light ray towards the normal of the surface at the point of entry.
When light enters a glass block, it undergoes reflection and refraction. However at the glass air interface, refraction occurs to a larger extent than refraction and hence some of the light is reflected while the rest of it enters the glass block.
When light enters a glass block, it slows down and bends (refracts) due to the change in medium density. As the light passes through the block, it continues to bend until it reaches the other side, where it exits the block and resumes its original speed and direction.
When a ray of light is shone at a glass block, it will refract (bend) as it enters the glass due to the change in the speed of light in the material. The light will then travel through the glass block, possibly reflecting off the surfaces inside, and refract again as it exits the block.
When a light ray enters a glass block, it will be refracted or bent due to the change in speed as it moves from one medium (air) to another (glass). This bending is caused by the change in the optical density of the two materials. The degree of bending depends on the angle at which the light ray enters the glass block.
When light is shined at a glass block, some of the light is transmitted through the block, some is reflected, and some is absorbed. The transmitted light changes its direction due to refraction as it passes through the glass block.
The ray of light gets refracted. Depending on the medium it is entering, it will bend either to or away from the normal. For example, if it is entering a glass block from air, it will bend towards the normal, and if it leaves a glass block and enters air it will bend away from the normal. The amount the ray bends depends on the angle of incidences and the refractive indices of the two mediums, and are governed by Snell's Law.
When light enters a glass block, some of it is reflected back, some is transmitted through the glass, and some is absorbed by the glass and converted into heat. The amount that is reflected, transmitted, and absorbed depends on the angle of incidence and the properties of the glass block.
