Traditional incandescent light bulbs were used for many years and produce bright light, but the bulbs rapidly become too hot to touch. Halogen bulbs are slightly more efficient. Compact fluorescent light bulbs (CFL) and Light-emitting diode light bulbs (LED)

generate less thermal energy. Based on this information, what types of bulbs are most likely indicated by the illustration

A)

incandescent and halogen

B)

incandescent and LED

halogen and CFL

D)

CFL and LED

Answer it orbits high above earth to gain clearer images of light, it magnifies images relative to the human eye, it records most of the universe as it was in the past, not as it is now;

1) what is light? light is an electromagnetic wave visible to the human eye.  2) what is a reflection? the rebounding of a light ray when it hits a mirror.3) what is the incident ray? contacts the surface of an object.4) what is the reflected ray? bounces off a reflective surface.5) what is the normal ray? perpendicular to the surface of a mirror.6) what is the angle of incidence? an angle formed by the incident ray and the normal.7) what is the angle of reflection? an angle formed by the reflected ray and the normal.8) what is refraction? (bending.)9) what is a converging lens? bring together light rays that pass through.10) what is a diverging lens? spreads out light passing through.11) focal point? the real point where the refracted rays meet when the incident rays run parallel.
