hands lens or hand lens
The objective lens is the part of the microscope that helps to make an object look larger by magnifying its image.
Objects appear larger underwater due to the refractive index of water. This causes light rays to bend as they pass through water, which makes objects look closer and larger than they actually are. Additionally, the distortion caused by the water can magnify the appearance of objects.
Lens.
Objects will look larger when viewed through the side of a water-filled glass due to refraction. Light bends as it passes through the water and then again when it enters the air, causing the object to appear magnified.
