A transparent optical tool that refracts light.
LENS
What is a lens?
The process in which light is separated into its colors due to the differences in the degrees of refraction.
DISPERSION
What is dispersion?
Absorb light, do not let the light to pass through.
OPAQUE
What is an opaque material?
Curved outward, like the underside of a spoon.
What is convex?
How to locate for Ray 1.
Parallel to the principal axis and reflects towards the focal point F.
The bending of light as it enters a new medium.
REFRACTION
What is refraction?
The combination of two or more light waves to form a resultant wave in which the displacement is either reinforced or cancelled.
INTERFERENCE
What is interference?
Allow light to easily pass through the materials.
TRANSPARENT
What is a transparent material?
Any smooth surface that reflects light well enough to produce an image.
What is a mirror?
How to locate for Ray 3.
Passes through the center of curvature C and reflects back at the same line.
Objects reflect what to become visible to your eye.
LIGHT
What is light?
This is the bending of light waves through small opening or around obstacles in its path.
DIFFRACTION
What is an diffraction?
Allow light to pass through but distorts the light during the passage.
TRANSLUCENT
What is a translucent material?
People suffering from nearsightedness use this type of lens.
CONCAVE LENS
What is a concave lens?
Describe the image formed of an object placed in the center of curvature.
L - same side of the object
O - inverted
S - same size
T - real
The second law of reflection.
The incident ray, reflected ray and the normal line should lie on the same plane.
Differentiate the two types of reflection.
SPECULAR - smooth surface/image is formed
DIFFUSE - rough surface/no image formed
What are specular and diffuse reflection?
Give three examples of transparent materials.
Water, Air, Glass
What are transparent materials?
A copy of an object formed by light.
IMAGE
What is an image?
Describe the image formed at focal point/focus.
There is no image formed/The image is formed at infinity.
This law states, "The angle at which light strikes a surface equals the angle at which it reflects off the surface."
FIRST LAW OF REFLECTION
What is the Law of Reflection?
The meeting and combining of waves; the adding or subtracting of wave amplitudes that occurs as waves overlap.
INTERFERENCE
What is interference?
They are said to transmit light in the absence of details. You can only see blur image when you peek through these.
TRANSLUCENT
What is a translucent material?
An image produced in a location where light does not actually reach.
VIRTUAL IMAGE
What is a virtual image?
Describe the image formed if an object is placed between C and F.
L - beyond C
O - inverted
S - enlarged
T - real
