no , and its not calld 'bend' its called 'reflected'
but its like bend but ITS NOT :)
Light reflects or bendsbecause it moves into different mediums
No, a light ray does not bend if it enters a glass block perpendicularly.
Maybe
The light will bend into an angle because of the shape of the glass and the location from which the light is coming from.
When light moves from air to glass, it will bend towards the normal. This is due to the increase in optical density as light enters the glass medium, causing it to slow down and change direction.
A prism?
some metals and glass
That's correct. Glass has a higher refractive index than air, which means that light travels at a slower speed in glass compared to air, causing it to bend more when passing from air to glass. This bending of light is also known as refraction.
When light travels from air into glass, it may not bend if it hits the glass surface perpendicular to it, which is called normal incidence. In this case, the speed of light doesn't change as it enters the glass, so there is no bending of the light ray. However, if the light hits the glass at an angle, it will bend due to the change in speed between air and glass, a phenomenon known as refraction.
bend at surface and continued in the same direction in bulk of it...and again bend at emerging surface.........
lenses bend light by having the light pass through the glass(or whatever material) of the lense in which the light will slow down. As the light enters the glass the very first part of the ray will slow down alowing other parts to catch up. This makes the light bend towards the normal (perpendicular to side of glass). As the light leaves the glass the oposite occurs. The light that leaves the glass goes faster leaving other parts behind and bending it away form the normal. How much the light bends depends on the shape of the lense the material of the lense and the angle that the light comes in at.
No, aluminum foil reflects more light than transparent glass. Aluminum foil has a high reflective surface that reflects a higher percentage of light compared to glass, which allows more light to pass through.
