Mirror (uses reflection principle), transparent glass sheet (uses refraction principle),etc are the instruments which are used to bend light.
A prism bends light
a spectograph
It is an instrument for measuring the intensity of light.
phonograph is a musical instrument. Phono means sound. Do you mean Photograph? That is a picture
Fold once, bend twice, three times over that, five bends diagonal, two bends vertical, and 9 bends horizontal. Then rap around pencil and unleash todays wonderful fold! P.S. You will need a big sheet of paper.
Red bends the least. If you look at a prism with a beam of light shining through it, you will see violet is bent the most. This due to the refractive index of the glass changing the wavelength. Velocity & frequency are components of wavelength. So the refractive index is a ratio by which the speed of light is changed. I am not sure if frequency is changed.
The science instrument is called Prism. It actually does not bend light. It separates the light into seven different colours.
It bends light.
Refraction
the light bends.
If something refracts light it bends it.
It bends.
violet
prism
A prism bends light rays. White light is made up of many different wave lengths of light. A prism bends each wave length a different amount, that is why different colors are produced from the output side of a prism.
Refraction is the process that bends light.
concave lens bends light rays away from the center
