Visible light and Filters

What does the color of an object depend on?

the wavelength of light reflected

Colors of visible light spectrum

Red

Orange

Yellow

Green

Cyan

Blue

Violet

What happens to light hitting Opaque objects?

do not transmit light

absorb some wavelengths

reflect others

What does the colour of an opaque object depend on?

Which wavelength is most strongly reflected

What wavelengths do white objects reflect?

all wavelengths of visible light equally

What wavelengths do black objects reflect?

none, absorbs all

Transparent and translucent objects

transmit light- can absorb or reflect light

How does a transparent/translucent object appear colorful?

depending on wavelength reflected

How do color filters work?

Only transmit certain wavelengths and absorbs rest

How do primary color filters work?

only transmit wavelengths of that color

How do non-primary color filters work?

transmit wavelengths of that color and wavelengths of primary colors that make it

What happens when you look at a different colored object through a filter of another color?

object would appear black as all light reflected would be absorbed by filter
