Light
Ray of light that enters a mirror
Incident ray
What it refraction
light passes through a different mediums and bends (angle of refraction)
A ray is incident on a plane mirror at an angle of 25 from the normal. The angle of reflection is ________________ from the normal.
25
Which lens makes light rays bend and meet
Converging
What is the atomic number of gold
79
Ray of light that leaves a mirror
Reflective ray
The speed of light is faster in the second medium, which way does the ray bend
bends away normal
How can you tell if a real image forms on a mirror?
-all lines from a point or object converge
-on same side mirror
Which focus is the real focus of a lens
Principle focus
A mixture is a substance in which there are two or more types of particles. What are 2 types of mixtures
Homogeneous and heterogenous.
Animals producing light through special tissues
Bioluminescence
Index of Refraction equation
n=c/v
A reference line that is perpendicular to the reflecting surface at the point
Normal
The difference in SALT for T for lenses
Real is side past the lens.
Virtual is on same side of lens.
Involves a substance changing its physical properties. No new substances are formed, and the change may be reversible.
Physical change
Rough surface where each light ray is reflected in a different direction and no clear reflected image is seen
Diffuse reflection
what c is always equal to (speed of light)
3.0 times 108 m/s
What is the law of reflection?
Angle of incidence always equals angle of reflection
What is the lens equation
1/f = 1/do + 1/di
What is the name of group 1 on the periodic table
Alkali metals
The range of all types of radiation such as visible light and radio waves.
Electromagnetic spectrum
What is called when the angle of incidence is greater than critical angle
Total Internal Reflection
Draw a ray diagram of an object in a convex mirror when its between F and the mirror.
Image is virtual, larger, upright
Use SALT to describe the image for a diverging lens that forms when the magnitude of the object distance is less than that of the lens' focal length?
Upright, smaller and virtual (A diverging lens always produces an image with the same characteristics, regardless of the object distance.)
These types of elements may be solid, gas, or liquid (bromine) at room temp. On the right side of periodic table.
Non-metals
