Answer:
Explanation:
Paheli and Boojho were waiting for their dinner. Boojho lifted a stainless steel plate and saw his image in it. Oh! This plate acts as a plane mirror. My image is erect and is of the same size. Pahel saw her image using the back of a steel spoon. Boojho look here! I can also see my erect image though it is smaller in size. This spoon also acts as a mirror of some kind, said Pahel. You can also use a spoon or any curved shining surface to see your image.
