Rainbow formation is to dispersion and total internal reflection

[@green-ci5dw]

Because hole is in center and the plate expand to all directions so reduces the diameter of the hole.

[@vijiev5174]

Sir.. metal plate hole questionnte answer increase thanneyano..kure sources angane parayunu.."When a circular metal is heated it expands circumferentially, but not radially. hence the size of the hole increases along with the plate size" - ingane kandu.

[@Academis]

My answer was wrong, right answer is Hole size will increase
