Light and Objects

Transparent

________: allows almost all light to go through, so can be seen through clearly.

Translucent

________: can be seen through, but not clearly; allows some light to go through, but some is also absorbed or reflected.

Opaque

________: does not allow light to pass through; all light is either absorbed or reflected.

Ideal black object

________: absorbs all visible light (opaque to visible light)

non luminous objects

All ________ which are colored appear so due to the fact that they absorb part of the incident radiation and reflect or transmit the remaining part to the observer; colors seen are those not absorbed.

light wave

When the ________ strikes an object, it interacts with that objects electrons, and the greater mobility of electrons, the greater the degree of interaction.

Transparent

________ colored objects: transmit only certain wavelengths of visible light and absorb the rest.

Opaque

________ colored objects: objects (________ or transparent)) have their colors because they selectively absorb all other colors except their own (this is the only color that is left unabsorbed)

Opaque

________ white and black objects: they appear white when they mainly reflect all the wavelengths of visible light.

Opaque

does not allow light to pass through; all light is either absorbed or reflected

Translucent

can be seen through, but not clearly; allows some light to go through, but some is also absorbed or reflected

Transparent

allows almost all light to go through, so can be seen through clearly

Transparent colorless objects

transmit all wavelengths of the visible spectrum (no absorbance); water, glass

Transparent colored objects

transmit only certain wavelengths of visible light and absorb the rest

Opaque white and black objects

they appear white when they mainly reflect all the wavelengths of visible light

Ideal black object

absorbs all visible light (opaque to visible light)

Grey object

partial absorbance and partial reflection of all frequencies of visible light

Opaque colored objects

objects (opaque or transparent)) have their colors because they selectively absorb all other colors except their own (this is the only color that is left unabsorbed)
