Visible Light Spectrum
This is the acronym used to remember the colors of the visible spectrum.
What is ROY G. BIV?
Which type of EM wave has the longest wavelength?
What are radio waves?
What does a prism do to white light?
What is splits it into the visible spectrum
The angle of incidence is always equal to the…?
What is the angle of reflection?
Light travels in what kind of wave?
What is a transverse wave?
A material that lets all light pass through so you can see clearly is called this.
What is transparent?
When light passes through a material, this process is called what?
What is transmission?
This color has the longest wavelength in the visible spectrum.
What is red?
Which wave can cause sunburns if you don’t wear sunscreen?
What are ultraviolet (UV) rays?
What is it called when light bends as it enters a new medium?
What is refraction?
The bouncing of light off a surface is called this.
What is reflection?
The top part of a wave is called this.
What is the crest?
A frosted glass shower door is an example of this type of material that lets some light through but scatters it.
What is translucent?
True or False — A single material can reflect, absorb, and transmit light at the same time.
What is true?
This color has the most energy and the shortest wavelength.
What is violet?
Which EM waves can pass through the body and are used in hospitals to see bones?
What are X-rays?
A straw looks bent in a glass of water because of this.
What is refraction?
What type of surface causes a clear reflection?
What is a smooth surface (like a mirror)?
The distance from one crest to the next is called what?
What is wavelength?
A brick wall is this type of material that lets no light through.
What is opaque?
A black T-shirt on a hot sunny day feels hotter because it mostly does this to light.
What is absorbs it?
What do we call the range of light that human eyes can see?
What is the visible light spectrum?
Which two types of EM radiation are just outside the visible spectrum?
What are infrared and ultraviolet?
When light passes through a prism, what causes it to spread into colors?
What is different wavelengths bending at different angles?
What do we call the incoming ray that strikes a surface?
What is the incident ray
This is the number of waves that pass a point in one second.
What is frequency?
When light hits a surface and bounces back, it’s called this.
What is reflection?
Sunglasses with mirrored lenses mostly do this to sunlight.
What is reflect it?
True or False – The visible light spectrum is the only part of the electromagnetic spectrum.
What is false?
Arrange these from longest to shortest wavelength: Gamma rays, radio waves, visible light.
What is radio waves, visible light, gamma rays?
Which color bends the most in a prism?
What is violet?
If the angle of incidence is 45°, what is the angle of reflection?
What is 45°?
What is the bottom of a transverse wave called?
What is the trough?
When a material takes in light energy instead of bouncing or letting it through, this is happening.
What is absorption?
If you put a red apple under green light, it looks dark because it mostly does what to the green light?
What is absorb it?
