Light rays bend upward when they pass through a medium where the refractive index decreases with increasing height, such as a temperature inversion in the atmosphere. This bending phenomenon is known as atmospheric refraction and can cause optical illusions like the mirage effect where distant objects appear elevated.

How do concave lenses bend light rays?
Concave lenses bend light rays outward (diverging) as they pass through, causing the rays to spread apart. This is due to the shape of the lens surface being thinner at the center than at the edges, which causes light rays to diverge.
What type of lens causes light rays to refract?
A convex lens causes light rays to converge, or refract, towards a focal point. This type of lens is thicker at the center than at the edges, causing light rays passing through it to bend inward.
Why refraction makes the image seen in lenses?
Refraction causes light rays to bend as they pass from one medium to another, such as air to glass in a lens. This bending of light rays helps focus the rays to form an image at the back of the lens. The shape of the lens determines how much the light rays bend and where the image will be formed.
What causes light rays to bend when they enter a new medium in a new angle?
Light rays bend when they enter a new medium at an angle due to refraction, which is caused by the change in speed of light as it travels from one medium to another with a different optical density. This change in speed causes the light rays to change direction, leading to bending.
What happens when light goes through cocave lens and convex lens?
When light passes through a concave lens, it diverges or spreads out. This causes the light rays to bend away from each other. In contrast, when light goes through a convex lens, it converges or comes together at a focal point. This causes the light rays to bend towards each other.

What causes light rays to bend when they enter a new medium at an angle?
Light rays bend when they enter a new medium at an angle because they either slow down or speed up. They speed up the most if they are in a vacuum.

Why light rays bend upward and downward in fresnal biprism?
Light rays in a Fresnel biprism bend upwards and downwards due to the differing refractive indices of the two prisms, causing the light to experience different speeds and angles of refraction. This results in the phenomenon of interference patterns when the light waves reunite due to the phase difference caused by this refraction.
Which light ray will bend the least when red green and blue light rays enter a drop of water?
Red light rays will bend the least when entering a drop of water, as red light has the longest wavelength of the visible light spectrum. Blue light rays will bend the most, as they have the shortest wavelength. Green light rays will bend somewhere in between red and blue.
Describe the behavior of light that enables magnifying lenses and contact lenses to bend light rays.?
Magnifying lenses and contact lenses are curved to alter the path of light rays passing through them. The curvature of the lens causes incoming light rays to converge or diverge, depending on the focal length of the lens, which enables the lens to bend the light rays and focus them onto a single point, resulting in magnification or correction of vision.
Causes light rays passing through it to meet at a focal point?
A converging lens causes light rays passing through it to meet at a focal point as a result of refraction. The lens is thicker in the center than at the edges, causing the light rays to bend towards the center and converge at the focal point.
Why do the light rays bend in water?
Light rays bend in water due to a change in the speed of light as it passes from one medium (air) to another (water) with a different optical density. This change in speed causes the light ray to change direction, a phenomenon known as refraction.
What process is pencils bend in the water?
When a pencil is placed in water, the light rays passing from air to water bend due to the change in medium. This bending of light rays causes the pencil to appear bent when viewed through the water-air interface. This is a phenomenon known as refraction.
