Physics Flashcards
What is an incident ray
a ray of light coming toward a surface
What is the angle of incidence
the angle between the incident ray and the normal
What is the normal
a perpendicular line drawn from the surface
what is a reflected ray
a ray of light that is a reflection of the incident ray
What is the angle of reflection
the angle between the reflected ray and the normal
how are the angle of reflection and angle of incidence connected
they are equal
How fast does light travel
3.00 x 10m/s
Why are shorter wavelengths dangerous
they have a higher form of energy
How are all the forms of energy created
by the sun
How does light travel
in straight lines
How can different objects affect light
they can cause the light to refract, reflect, or get absorbed
What is diffuse reflection
when light is reflected off a rough surface
What happens during diffuse reflection
light bounces off randomly
