Exploring the Colors of Light

What is the visible spectrum of light?

• The visible spectrum of light ranges from 750 nm to 1000 nm.

• The visible spectrum of light ranges from 380 nm to 750 nm.

• The visible spectrum of light is only visible in complete darkness.

• The visible spectrum of light ranges from 100 nm to 300 nm.

How do colors appear when light is refracted?

• Colors disappear completely when light is refracted.

• Colors remain unchanged when light passes through a prism.

• All colors blend together and appear white when refracted.

• Colors appear separated and spread out due to the varying degrees of refraction of different wavelengths of light.

What is the primary color of light?

• Green

• Yellow

• Red

• Blue

What happens when white light passes through a prism?

• White light is absorbed by the prism.

• White light is dispersed into a spectrum of colors when it passes through a prism.

• White light remains unchanged when passing through a prism.

• White light is reflected back without any change.

What is the difference between additive and subtractive color mixing?

• Additive mixing uses pigments to create colors, while subtractive mixing uses light.

• Additive mixing absorbs light to create colors, while subtractive mixing reflects light.

• Additive mixing combines light to create colors, while subtractive mixing combines pigments to absorb light.

• Additive mixing is used in printing, while subtractive mixing is used in digital displays.

How does the color of an object change under different lighting conditions?

• The color of an object changes due to variations in light sources and their wavelengths, affecting how colors are perceived.

• The color of an object remains the same regardless of lighting.

• Lighting has no effect on how colors are perceived.

• Colors are determined solely by the object's material composition.

What is the role of pigments in color perception?

• Pigments only affect color perception in artificial light.

• Pigments determine color perception by absorbing and reflecting specific wavelengths of light.

• Pigments are responsible for the texture of objects.

• Pigments enhance color perception by increasing brightness.

What are complementary colors in light?

• Black, White, Gray

• Red, Green, Blue

• Orange, Purple, Brown

• Cyan, Magenta, Yellow (complementary to Red, Green, Blue respectively)

How does the human eye perceive color?

• The human eye uses only rods to detect color.

• Color perception is solely determined by the brightness of light.

• The human eye perceives color through the lens that filters light.

• The human eye perceives color through three types of cones in the retina that respond to different wavelengths of light.

What is the significance of the color temperature of light?

• Color temperature only affects the brightness of light.

• The significance of color temperature lies in its impact on mood, perception, and visual clarity in various applications.

• It determines the physical size of light sources.

• Color temperature is irrelevant in photography.
