Why do light colored objects feel cooler than dark colored objects?
Because dark colours absorbs light/heat, while light colours reflect light/heat.
A prism breaks white light into what?
A dispersive prism can break light into its spectral colours, or the colours of the rainbow
What object does not break up light into its colours?
A single dimensional shape.
Which surface are light rays reflected?
Any opaque or translucent surface will reflect light rays. The rays that are reflected are the one that you see- something blue would reflect blue light. IF the object is Opaque the rest of the light is absorbed. If it is translucent some light is absorbed while some passes through. Black objects absorb all colours of light while white objects reflects all colours of light. There are also some special objects such as mirrors that are highly reflective a produce an image by reflecting back the rays of light emitted from other objects.
What happens when light falls on a white objects?
We see colours because of white light (visible light) which is made up of red, orange, yellow, green, blue, purple light. We see colours when some fo these colours are absorbed into the object and the others are reflected. If an object is white that means all the light reflects off the object

What color light makes objects look bigger?
light colours - white is bestdark colours make a room look smaller.
Why do a yellow bus appear yellow?
Colours appear the way they are because of light. Objects such as this bus reflect colours from light..thats why most things apear black in the dark because there is little or no light to reflect off of. Yellow objects reflect yellow while absorbing remaining colours
What object does not break up light into its colours?
A single dimensional shape.
What is the break up of white light into seven colours?
It is the refraction of white light being shone through a glass prism, or a raindrop, that separates the white light into the colours of the rainbow.
Why do colours of objects look different in the night?
there is no light to reflect off the object that you want to see
How does light allow us to see?
Objects absorb light at certain frequencies and reflects light at other frequencies. The reason we see colours is because that is the frequency of light reflected, the reason we see black is because all colours are absorbed....it's nothing. So the reason we see objects is because light is reflected from them, this light then meets our eyes and creates an image.

What device do scientists use to break white light into its colours?
They can use a kind of glass/cristal named Prisma
What are the everyday objects which absorbs the colors in sunlight?
All visible objects with a defined color absorb colours of the sunlight. If you see e.g. a red box, it absorbs all the green and blue parts of the sun light. While black objects absorb all colours (and therefore get most hot), white objects absorb almost nothing, so keeping cool.
