What part of the eye does light pass through?
the light travels through the conjunctiva,cornea,aques humour , pupil,the lens and the vitreous humour. it will also partially travel through the retina.
What happens to light rays as they pass through lenses?
well it encounters the lens and adjusts thickness to focus
When a light ray strikes the eye what part of the eye does it first pass through?
The cornea is the clear part of the outer tunic of the eye through which light passes.
What does a beam of light pass throgh to get to the retina?
The cornea is the clear front surface of the eye, which acts like a camera lens, and allows light through to reach the retina.
How do lenses affect light?
bend it
What does a convex lens do to light rays when they pass through them?
correct
Does light pass through the convex lens in a reflector telescope?
yes
Parallel light rays that pass through a convex lens are?
Converging. Tip: look at the pictures and read : http://en.wikipedia.org/wiki/Lens_(optics)
How light rays traveling parallel to the optical axis are bent after they pass through a convex lens?
After they pass through the lens, they converge, meaning that they come together at a specific point.
Do Light Rays converge or diverge?
Light rays converge as well as diverge. it depends upon the type of lens or mirror you pass it through. A concave lens or a convex mirror diverges the light whereas a convex lens or a concave mirror converges the light rays!
Do all light waves that strike a convex lens pass through the focal point?
Only if they enter the lens in the direction parallel to its axis.
Do all light waves that travel through a convex lens always pass through the focal point?
No, not all light waves that travel through a convex lens pass through the focal point. It depends on the wavelength of the light, since light of different wavelengths diffract at different angles when encountering a change in media, such as air to glass, at an angle. Isaac Newton noted this in his study of light and prisms.
What happens to light that passes through a convex lens?
Light travelling through a concave lens will spread out. In most optical systems that use a concave lens, such as a telescope that needs to magnify the focal plane image, this is a desirable effect.
What is a Convex lens-?
It is a lens that possesses at least one surface that curves outwards. It causes light to deviate inward, bringing the rays of light to a focus. Its thicker at its center than at its edges, and is used to correct far-sightedness. A convex lens is a lens that bulges outward on both sides. I have another comment. It does do all that stuff and who needed them to build a telescope? It's Galileo Galilie. Ohyah!
What is the differebetween a lens and a mirror?
a lens will focus the light to a point or will disperse it(concave or convex lens) same as with a mirror, tho lens have a differnce, they are transparent and will let the light rays pass through themand form a real image behind the lens, while a mirror cannot.
What happens to light rays that travel parallel to optical axis as they pass through a convex lens?
The rays are diffracted toward the center of the lens. This is the principal used in reading and magnifying glasses.
How does a telescope form an image?
by refracting light rays that pass through it
