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

answer: c. the experiment shows that the red substance experienced a chemical change.

explanation: chemical change is the change in which chemical composition of the substance changes. physical change is the change in which there is no change in chemical composition.

chemical changes are accompanied by following changes:

a) precipitate formation

b) energy is released or absorbed

c) formation of bubbles

d) change in color

as it is given that the red color has disappeared and there is production of gas, it means the red substance has undergone a chemical change.
