The continuous range of electromagnetic waves arranged in order of frequency or wavelength.

Which wave has the longest wavelength?

Which type of UV ray penetrates deeper through the skin?

The bouncing back of light into the same medium it has been traveling after striking a surface.

Which of the pair produces the same image?

The image formed when the object is pass the focal point of a concave mirror.

Image formed by a convex mirror when the object is very far away.

Plane mirrors produce what kind of image.

Medical term for nearsightedness.

If you go fishing with a bow and arrow, will you aim directly at the fish, above the fish, or below the fish to hit it?

An electrical motor changes mechanical energy into electrical energy

You use telescopes to look at near objects

An AC generator does not use a commutator

n=c/v

The optical density of a material is not indicated by its index of refraction or refractive index, the ratio of the speed of light in a vacuum to that in the material.

Another interesting effect of refraction is the shallowing effect. Objects submerged in a liquid always appear to be shallower than they actually are.

The angle of incidence corresponding to an angle of refraction of 90° is called the critical angle.

If the angle of incidence is greater than the critical angle, no refraction occurs. The light will be totally reflected back to the first medium. This phenomenon is called total internal reflection.

A virtual image is always erect.

The hollow part of a shiny spoon is a concave mirror

Night driving is easier when the road is wet

According to one of the laws of refraction, the incident ray, the refracted ray, and the normal all lie on the same plane.

Reflection from rough surfaces is called diffuse reflection

The angle of incidence is equal to the angle of refraction

Danish physicist and chemist ___________ accidentally discovered that an electric current produces a magnetic field.

Faraday's law states that a change in the strength of a magnetic field, also known as __________, induces a current (and hence induced emf).

A magnifying glass is often combined with another converging lens to achieve greater magnification. The result is an optical device called a _____________.

Isaac Newton invented the __________ in 1668. Instead of a converging lens, a concave mirror was used as the objective.

_________ is the process of removing electrons from neutral atoms.

To find the energy of an EM wave, you use

To find the position of an image, you use the mirror equation.

Which of these is true?

Which of these is the formula for magnification of a magnifying glass?

What is the formula to find the infuced EMF?

The most acute sense of vision is at the _________

Which part of the eye has the same function as the film or digital sensor array of a camera?

Light that enters the eye is refracted mostly at the ________

The image formed on the retina is real, inverted, and smaller than the object

The ciliary muscles are not responsible for changing the shape of the crystalline lens.

Which part of the eye is the colored circle?

The _______ is the thin, transparent tissue that lines the inner surfaces of the eyelids and the outer surface of the eyeball.

What is between the cornea and the lens?

It is composed of layers of blood vessels and connective tissues.

between sclera and retina c:

What part of the eye regulates the amount of light entering the eye?

What part of the eye regulates the size of the pupil through contraction or relaxation of its muscles?

The ability of the crystalline lens to change its size when focusing on objects at different distances.

The point in the retina where the optic nerves exit.

Rods are used to see in the dark, while cones are used to see in the dark.
