EM Spectrum
This type of radiation is responsible for sunburns
What is UV light?
This structure is a small opening that allows light into your eye
The sun shines through your windshield and hits your eyes
What is transmission?
A device which produces a powerful, narrow beam of light
What is a laser?
The light from a laser can only be one of this
What is wavelength OR colour?
Your cell phone uses this type of radiation to speak to your airpods
What are radio waves?
A strongly curved cornea produces this visual disorder, causing objects which are far away to appear blurry
What is myopia?
You try to grab a rock underwater and miss
What is refraction (aka bending)
Unlike a laser beam, light from this device spreads outwards
What is a flashlight?
This is the shortest wavelength of visible light
What is red?
This type of radiation will kill you almost instantly in high doses
What are gamma rays?
An irregularly shaped cornea produces this disorder responsible for blurry vision
What is astigmatism?
A tree's leaves are green
What is reflection?
Lasers which send pulses of information along wires into homes
What is fibre optics?
Before laser eye surgery, this surgical procedure helped correct vision
What is removing the cornea with a knife and boiling it?
This type of radiation is commonly used in medical imaging
What are X-rays?
This structure turns movement into electrical signals and sends them to the brain
What is the retina?
Pavement gets hot on a summer day
What is absorption?
Wording used to describe how all the waves of a laser line up
What is "in-step?"
When multiple wavelengths of visible light are blocked or absorbed (by a glass pane, for example), they produce a new colour
What is the Subtractive Theory of Colour?
This type of radiation is found throughout space as evidence of the Big Bang
What are microwaves?
This structure, held within the retina detects colour
What are cones?
Mr. Carver’s glasses correct his vision
What is refraction?
The acronym which creates LASER
What is Light Amplification by Stimulation of Emitted Radiation?
An object which reflects 100% of light
What is a mirror?
