Reflecting Light

Textbook pages 28-32 INB pages 80-86

angle of incidence

the angle at which the incident beam hits a mirror

angle of reflection

the angle at which the reflected beam leaves the mirror

photon

a packet of energy

rays

light waves that travel in straight lines. If they are not stopped, they will travel forever

Incident beam

light from a source

reflected beam

light reflected off a mirror

True or False: Is the angle of incidence equal to the angle of reflection?

True

What is a common mnemonic for the visible light spectrum?

Roy G Biv

What is type of electromagnetic wave has the highest energy?

Gamma rays

What is the lowest energy electromagnetic wave?

Radio waves

True or False: fluorescent light has a better quality of light than The Sun.

False

What are the seven parts of the electromagnetic spectrum from lowest to highest energy

Radio, Microwave, Infrared, visible, Ultraviolet, X-Ray, Gamma

What are some examples of sources of light

The Sun, Lightbulbs, Lasers, Fire, Bioluminescent animals

What colors will you see if you look at something with a red filter

Only Red

What color is the human eye most sensitive to

Yellow and Green

What is the longest wavelength of visible light?

Red ~700 nanometers

Normal Line

a line that extends at a right angle from a flat surface

What is a spectroscope used for?

breaks the light from a single material into its component colors the way a prism splits white light into a rainbow

Transparent

materials that are clear and let light through
