Light Wave Video

What is light described as in terms of its physical properties?

• Electromagnetic radiation that behaves like both a wave and a particle

• A type of sound wave

• Only a particle

• A form of matter

What determines the energy of a light wave?

• Its color

• The medium it travels through

• Its wavelength and frequency

• The speed it travels at

What role do cones in the retina play?

• They are sensitive to different energies of light, determining color

• They protect the eye from harmful radiation

• They detect sound waves

• They measure brightness

Why can't humans see all wavelengths of light?

• Due to the energy level not matching our retina's capabilities

• Because light outside the visible spectrum doesn't exist

• Our eyes are only sensitive to sound waves

• Because of the color of the light

How do we observe light beyond the visible spectrum?

• Listening for it with radio antennas

• Through special detectors and telescopes

• Using our eyes during the night

• By using microscopes
