The color that is bent the least by a prism is violet blue yellow red

Answer : The correct option is, Red

Explanation :

Prism : It is defined as the two plane surfaces inclined at an angle with respect to each other.

Or we can say that prism is a type of glass in which the while light is refracted through the prism, it splits into different colors with different wavelength and frequency. The color observed through prism are violet, indigo, blue, green, yellow, orange and red (VIBGYOR).

The increasing order of bending the light by a prism are :

Red < Orange < Yellow < Green < Blue < Indigo < violet

That means the color that is bent the least by a prism is, red color and the color that is bent the most by a prism is, violet color.

Hence, the correct option is, Red

we can conclude that the melting point of table salt is above room temperature (it's actually 801 deg c). the melting point of mercury must be below room temperature (- 39 deg c).
