Light traveling through a lens appears to converge or diverge depending on the shape of the lens. In a converging lens, the light rays come together at a focal point after passing through the lens, whereas in a diverging lens, the light rays spread out. The path of light through a lens can be visualized using ray diagrams.

Why do light rays pass through a lens change direction?
If a wave of light is reflected by an opaque material, it changes direction. If it refracts (like light going from air into water), it can change direction. Also, gravity can bend light. For example, a black hole can trap light.
What is the disturbance that transfers energy through a field?
A wave is the disturbance that transfers energy through a field. Waves can be mechanical, like sound waves traveling through air, or electromagnetic, like light waves traveling through space.
Does a magnifying glass reflect or refract?
A magnifying glass refracts light. When light passes through the lens of a magnifying glass, it is bent or refracted, which causes objects to appear larger when viewed through the lens. Reflection occurs when light bounces off a surface, like a mirror.
2 What type of lens does a drop of water behave like?
A drop of water behaves like a convex lens, which causes light passing through it to converge and form an image. This bending of light is due to the differences in refractive indices between the air and water.
Explain the shape of a concave lens and a convex lens?
A convex lens is thicker in the center than at the edges. A convex lens is like a concave mirror.A concave lens is thinner in the center than at the edges.
What is it called when light travels through the lens of a telescope?
The phenomenon where light travels through the lens of a telescope is called refraction. Refraction occurs when light passes through a medium like glass, causing the light rays to bend and converge or diverge to form an image.

What is the function of pupil in human eye?
. The pupil is an adjustable opening that controls the intensity of light permitted to strike the lens. The lens focuses light through the vitreous humor, a clear gel-like substance that fills the back of the eye and supports the retina

How light rays traveling parallel to the optical axis are bent after they pass through a convex lens?
When light rays travel parallel to the optical axis and pass through a convex lens, they converge at a focal point on the opposite side of the lens. This is due to the convex shape of the lens causing the light rays to refract towards the center of the lens. The point at which the light rays converge is known as the focal point, and the distance between the lens and the focal point is called the focal length. This phenomenon is governed by the lens equation, which relates the object distance, image distance, and focal length of the lens.
What is concave lens?
a lens that caves in like this )( as opposed to convex which puffs out like this (). a concave lens. it is used to bend and focus light
What is the function of the lens?
The lens in our eye is 10x and it's a concave lens. When the light goes through it, the light bends.
How do you expect the light wave to travel differently?
Light waves can travel through different mediums, such as air, water, and glass. The speed and direction of light waves can change depending on the medium they are traveling through due to factors like refraction and reflection. The wavelength and frequency of light waves remain constant regardless of the medium they are traveling through.
What happens when light rays pass through concave lens?
When light rays pass through a concave lens, they diverge (spread out) rather than converge (come together). This causes the image formed by the concave lens to appear smaller and virtual (cannot be projected onto a screen). The lens is used to correct conditions like myopia (nearsightedness) by reducing the focusing power of the eye.
