General Knowledge
This form of energy is constantly moving throughout the universe in waves.
What is light energy?
The highest point of a wave is called this.
What is the crest?
This scientist used a prism to separate white sunlight into many different colors in 1672.
Who is Isaac Newton?
This type of mirror reflects light in such a way that it makes the image appear larger.
What is a concave mirror?
These are the longest electromagnetic waves and are used for radio and television broadcasting.
What are radio waves?
These are the primary colors of light.
What are red, green, and blue?
These waves can travel through both matter and empty space.
What are electromagnetic waves?
The lowest point of a wave is called this.
What is the trough?
This acronym helps you remember the order of colors in the visible spectrum.
What is "ROY G. BIV"?
This type of mirror reflects light and makes the image appear smaller than the object.
What is a convex mirror?
These shorter wavelength waves are used to heat food in microwave ovens.
What are microwaves?
These are the primary colors of pigments.
What are yellow, cyan, and magenta?
This is the name for waves that can only travel through matter, like sound.
What are mechanical waves?
This property of a wave measures the distance between two crests or troughs.
What is wavelength?
This color in the visible spectrum has the shortest wavelength.
What is violet?
This common mirror type creates an image that looks exactly like the object, only reversed.
What is a plane mirror?
This type of wave has a wavelength just shorter than visible light and can be used for thermal imaging.
What are infrared waves?
When red, green, and blue light are mixed together in equal amounts, this color is formed.
What is white?
Light travels through space and can reach Earth in approximately this amount of time from the Sun.
What is 8 minutes?
The height of a wave is called this.
What is amplitude?
This color in the visible spectrum has the longest wavelength.
What is red?
When a light bounces off a smooth, shiny surface at an equal angle in the opposite direction, this happens.
What is reflection?
These waves are responsible for the UV rays that cause sunburn.
What are ultraviolet rays?
This happens when you mix pigments together.
What is creating a dark, almost black color?
This type of wave, like sound, moves in the same direction as the vibration.
What are longitudinal waves?
This property of a wave refers to how many waves pass a point in one second.
What is frequency?
This type of light change happens when light passes through a raindrop and bends, creating a rainbow.
What is refraction?
This everyday object uses concave mirrors to magnify an image, often used for grooming.
What is a makeup mirror?
These waves are shorter than ultraviolet rays and can be used to detect cracks in materials like steel.
What are X-rays?
The complementary color of red light is this.
What is cyan?
Light waves are this type of wave, moving perpendicular to the direction of vibration.
What are transverse waves?
This property measures how far one wave travels in one second.
What is speed?
This process occurs when light changes direction as it passes from one medium to another.
What is refraction?
What instrument uses mirrors to help see things in outer space
What is a telescope?
These rays are used in hospitals to sterilize medical equipment.
What are gamma rays?
This light ray helps produce Vitamin D in the skin but can also cause sunburn and skin damage if overexposed.
What are ultraviolet rays?
