Light and Color

What is light?

• Light is a form of energy.

• Light is a type of sound.

• Light is a solid object.

• Light is a form of water.

What is the difference between primary and secondary colors of light?

• Primary colors of light can be combined to create secondary colors.

• Secondary colors of light are brighter than primary colors.

• Primary colors of light are only red and blue.

• Secondary colors of light cannot be created from primary colors.

What is the role of prisms in relation to light?

• Prisms can absorb light and prevent it from passing through.

• Prisms can refract light and separate it into its component colors, creating a spectrum.

• Prisms can reflect light and enhance its brightness.

• Prisms can emit light and create a glow.

Why does a pencil appear broken when placed in a glass of water?

• The pencil appears broken because it is actually broken.

• The pencil appears broken due to the reflection of light.

• The pencil appears broken because light rays are bent when they pass from air into water.

• The pencil appears broken because of the color of the water.

What is the color temperature of light?

• A characteristic of visible light measured in Kelvin (K)

• The brightness of light measured in lumens

• The intensity of light measured in candelas

• The wavelength of light measured in nanometers

What is the principle of subtractive color mixing?

• A process of mixing colors using light sources

• A method of creating colors by adding pigments

• A technique where colors are created by subtracting wavelengths of light using cyan, magenta, and yellow

• A way to mix colors that only involves primary colors of light

What is the visible spectrum?

• The portion of the electromagnetic spectrum that can be seen by the human eye, typically ranging from about 380 nm to 750 nm in wavelength.

• The range of wavelengths that are invisible to the human eye, including ultraviolet and infrared light.

• The spectrum of light that is emitted by the sun, which includes all colors of the rainbow.

• The part of the electromagnetic spectrum that is used for radio communication, typically ranging from 30 Hz to 300 GHz.

What is the difference between transparent, translucent, and opaque materials?

• Transparent materials allow light to pass through clearly.

• Translucent materials do not allow any light to pass through.

• Opaque materials allow some light to pass through but not clearly.

• Transparent materials allow some light to pass through but not clearly.

What is the principle of additive color mixing?

• Additive color mixing is the process of combining different colors of light, where the primary colors (red, green, blue) combine to create other colors.

• Additive color mixing involves mixing pigments to create new colors.

• Additive color mixing is the method of blending colors in painting.

• Additive color mixing refers to the process of mixing colors in printing.

What happens to colors when you see the color black?

• All colors are reflected.

• All colors are absorbed.

• Only red is absorbed.

• Only blue is reflected.
