Challenge/Trick Questions
What is a stream of electrically charged particles from the sun?
solar wind
ROY G BIV represents the colors of the electromagnetic spectrum. What are the colors of the electromagnetic spectrum?
Red Orange Yellow Green Blue Indigo Violet
When light hits a mirror and bounces off, you are seeing a _______________
reflection
When light bends after hitting an object, it is known as _________________
Refraction
What do you call a material that lets some, but not all light pass through?
Translucent
when particles from the sun strike earth, it creates an electromagnetic reaction known as the _________________
Northern Lights/Aurora Borealis
What is the transfer of Energy as EM waves?
Radiation
What type of mirror is curved inward like the bowl of a spoon?
Concave
If matter lets all/most light pass through it, it would be considered _____________________
Transparent
Reflection/Reflecting
Explain the Law of Reflection
Whatever angle light hits a surface at, it will reflect back at the same angle
This word means "below red" and has longer wavelengths than Red light
Infrared
What type of mirror is curved outwards?
Convex
If Matter lets no light pass through it, it would be considered ______________________
Opaque
What is the exact speed of the speed of light (in Meters per second) NO Unit of measurement = Wrong
300,000,000 M/S
What is the difference between a virtual image and a real image
Virtual - comes from a place where the light does not originate
Real - Comes from a place where the light source originates
What EM waves have the shortest wavelength
Gamma Rays
What is a clear optical tool that refracts light?
Lens
What is the transfer of light energy to matter?
Absorption
If You are wearing a black shirt, what is happening to the visible light spectrum as it hits your shirt?
The shirt absorbs all colors of the spectrum, which makes the color black.
Why do astronauts have a thin layer of pure gold on their space helmets? (Hint: It's not for the drip, astronauts believe Skill >> Drip)
Gold reflects all UV radiation
Why is the sky blue (In order to receive full points, you MUST use correct terminology)
Blue light has the shortest wavelength, so when the Visible Light spectrum reaches earth, it refracts the most, causing it to scatter the most. (answer may vary slightly)
Explain the difference between a convex and a concave mirror
convex - Rounded at the edges
Concave - rounded in the middle
What do you call it When light is sent in many directions as it passes through a medium?
Scattering
Explain why astronauts use Gamma Rays to communicate in space
They don't use gamma rays, they use radio waves (Trick question to BAMBOOZLE my students)
