A cylinder’s geometry consists of two circular bases and a curved surface. Its lateral surface area is , while the total surface area, including the bases, is . The volume is calculated as , where  is radius and  height. #science #mathematics #10thclass

Refraction is the bending of light as it passes from one medium to another, caused by a change in speed. This phenomenon is responsible for effects like the distortion of objects underwater. Total internal reflection occurs when light attempts to move from a denser to a less dense medium at an angle greater than the critical angle, causing it to reflect entirely back into the denser medium. This principle is used in optical fibers and prisms.
