Question

what is meant by angle of the prism​

Answer 1

Answer:Hey mate answer is below mark me as brainliest

Explanation:

The angle between its two lateral faces is called the angle of the prism or the prism angle. When the light ray is allowed to pass through the prism, it makes the emergent ray bend at an angle to the direction of the incident ray. This angle is called the angle of deviation for the prism

Answer 2

$\begin{lgathered}\boxed{\begin{minipage}{5 cm}\bf{The angle between its two lateral faces is called the angle of the prism or the prism angle. When the light ray is allowed to pass through the prism, it makes the emergent ray bend at an angle to the direction of the incident ray. }\end{minipage}}\end{lgathered}$      

$\begin{lgathered}\boxed{\begin{minipage}{5 cm}\bf{The formula for the volume of a prism is V=Bh , where B is the base area and h is the height. The base of the prism is a rectangle. The length of the rectangle is 9 cm and the width is 7 cm. }\end{minipage}}\end{lgathered}$
