It is a form of energy you can see
a) Ray
b) Basic principle of light
b) Light
c) Fluorescent
What is a) Light?
It is the angles between the incident and reflected rays and the normal.
What is an angle of incidence and an angle of reflection?
It is the Angle of Refraction.
What is the new direction of light?
Light is a form of energy.
What is the first basic principle of light?
It is the definition of convex mirror.
What is a mirror that curves outward?
It is the definition of refraction.
What is the bending of light when it travels from one medium to another?
Define the word "ray"
What is a straight imaginary line that represents the path of a beam of light?
It is the Law of Reflection
Why does The angle of reflection=The angle of incidence?
TRUE OR FALSE?
Temperature does not affect refraction.
What is false?
It is when you heat an object to a high temperature until it emits light.
What is incandescent?
The ray that comes from a light source and strikes the surface.
What is an incident ray?
It is the reason light bends?
When does light bend because it changes speeds when going through different materials with different densities?
COST OF LIGHTING - It is the blank
Step 1: Convert Watts to kilowatts by dividing (by 1000)
Step 2: ____________________?
Step 3: Multiply the number of Kwh by the cents/hour
What is multiplying kW by hours?
It is the definition of Normal Line
What divides the angle of incidence and the angle of reflection into two equal angles and is perpendicular to plane mirror?
TRUE OR FALSE
When the angle of incidence increases, the angle of reflection increases.
What is false?
