Define SALT
Mirror that curves inward is called__
Concave Mirror
Mirror that curves outward is called____
Convex Mirror
What is Refraction?
A wave changes (bends) direction as it moves from one medium to another due to its change in speed.
In what form of waves does light travel?
Electromagnetic waves
According to the Law of Reflection, what is the angle of incidence equal to?
Angle of Reflection
What happens to the image when an object is placed at the focal point of a concave mirror?
No image is formed because the reflected rays are parallel
Why are vehicle mirrors convex?
Provide a wider view - blindspots
Index of refraction formula
n = c/v
Which color in the visible spectrum has the shortest wavelength?
Violet
The imaginary line perpendicular to a reflecting surface is called _____.
What type of mirror is a concave mirror: converging or diverging?
Converging
What will the size of a convex image always be?
Smaller than the actual object
Why does refraction not occur at 90 degrees?
The wave at 90 degrees means that it is overlapping the normal and parallel to it.
