Reflection and mirrors

___________________________ occurs when light hits an irregular surface.

• diffuse reflection

• regular reflection

• no reflection

___________________________ occurs when light hits a smooth surface.

• diffuse reflection

• regular reflection

• no reflection

What do you call a flat mirror?

• plane mirror

• convex mirror

• concave mirror

According to the Law of reflection, a light ray striking a mirror

• continues moving through the mirror in the same direction
• moves into the mirror at a slightly different angle
• bounces off the mirror toward the direction it came from
• bounces off the mirror at the same angle it hits.

The fact the two angles are the same is an example of....

• Refraction
• Angle of Incidence
• Law of reflection
• Magnification

How does light travel

• It curves around corners
• Really slow
• In a straight line
• In circles

....................... - the imaginary line perpendicular to the surface.

• Normal
• Angle of incidence 
• Angle of reflection

........... – the angle between the normal and the reflected ray.

• Angle of incidence
• Angle of reflection
• Angle of coincidence
• Angle of direction

Law of reflection state that - The angle of incidence is .................. to the angle of reflection.

• equal
• double
• half

What is the difference between diffuse and regular reflection

• Diffuse reflection is off a rough surface and its rays reflect in different directions. Regular reflection is off a smooth surface and its rays are parallel.

• Diffuse reflection is off a smooth surface and its rays reflect in different directions. Regular reflection is off a rough surface and its rays are parallel.

• Diffuse reflection is off a rough surface and its rays reflect in parallel. Regular reflection is off a smooth surface and its rays are dispersed.
