Properties of EMR
This is the form that ALL electromagnetic radiation takes.
What is waves?
This is the part of the eye located in the back where light is focused.
What is the retina?
This is the type of light that is released from a hot object like a flame.
What is incandescent light?
y=3x. If x=2, what is y?
What is y=6?
6=x/2. What is x?
What is x=12?
This is the speed at which all types of EMR travels.
What is the speed of light (300,000,000 m/s)
These are the two types of photoreceptor cells located in our eyes.
What are rods and cones?
This is the type of light that is released from objects that are not so hot that they are glowing.
What is luminescent light?
6=2x. What is x?
What is x=3?
y=x/3. If x=27, what is y?
What is y=9?
This is the ONLY difference between all the types of EMR.
What is wavelength?
This is the particular type of photoreceptor cell that detects colour.
What are cones?
This is the name of the process by which organisms create their own light (fireflies for example).
What is bioluminescence?
y=14x. If x=2, what is y?
What is y=28?
33=x/2. What is x?
What is x=66?
True or false: only some types of EMR travel in a straight line.
What is false?
This is the colour of light with a wavelength of 530 nm.
What is green?
This is the process by which light is released as a result of a chemical reaction.
What is chemiluminescence?
44=11x. What is x?
What is x=4?
44=x/3. What is x?
What is x=132?
This is the only type of EMR that we can see with our eyes.
What is (visible) light?
This is the colour of light with a wavelength of 320 nm.
What is invisible?
This is the type of lightbulb that works by heating up a filament until it glows.
What is an incandescent lightbulb?
y=11x. If x=5, what is y?
What is y=55?
45=x/2. What is x?
What is x=90?
