The question seems to be based on a misunderstanding.
A prism is used primarily for refraction, not reflection.
Second, you can (and do) use light of any colour, not just red.
The ball itself doesn't actually have a color. It simply has got the ability to reflect Red light, and we see it as having a red color. Light is buildt up by different wavelengts of light known as colors. All colors together form a warm white light. You can see the different colors of the sunlight if you use a prism. In any case, if you use only a blue light, Only the wavelength for blue, then the ball will appear Black because Blue does not have any Red in it. The Ball can not reflect red light if there is no red light to reflect :-)
Plants are green because the reflect green light. They do not use green light, they use red light to make food. Some plastic mulches are red to reflect red light onto plants to make them grow more.
You can use a prism to separate visible light into its different colors through the process of refraction. This creates a rainbow-like spectrum of colors ranging from red to violet.
WHEN AN UN POLARISED LIGHT IS MADE TO FALL ON A NICOL PRISM.(NICOL PRISM MADE UP OF CALCITE CRYSTA)if the light is split up into two Waves is o-ray and other is e-ray when we observe that the light is polarised because .the ordinary ray is after falling it will split into two rays one ray has only arrow component .other ray having only dot component this way we can say that Nicol prism acts as polarise
triangular prism
You can make a rainbow in the classroom with a prism or a glass of water by shining light through it. When light passes through, it refracts and separates into different colors creating a rainbow effect on a surface. Another way is to use colored paper or fabric to create a rainbow display on a wall.
get a glass prism and use a flashlight to point the light through it (p.s you can use a piece of glass to use as a prism)
To create a beautiful display of colors like a rainbow, you can use a prism or water droplets to refract sunlight into its different wavelengths, which will create the spectrum of colors. This can be done by shining sunlight through a prism or creating a mist of water droplets to reflect and refract the light.
glass prism re used 4 physics practicals
bcoz in triangular prism, sides are not parallel so rays will deflect but in rectangular prism sides are parallel so rays won't deflect instead they will pass straight.
1st you have to have the unison attack, then put 2 or more certain techniques together, for example, with Genis and Raine, Genis use Ground Dasher then immediately use Raine's Ray then it will make Prism Stars.
Red mostly. Leaves appear green to us because plants don't use it and reflect it away.
