QUESTION (i) When using a \( 10 \times \) ocular lens and a \( 40 \times \) objective, the total magnification achieved is

To calculate the total magnification, simply multiply the magnification of the ocular lens by that of the objective lens. So, with a \( 10 \times \) ocular lens and a \( 40 \times \) objective lens, the total magnification is \( 10 \times 40 = 400 \times \). This means that your specimen will appear 400 times larger than it does to the naked eye—a true gate to the microscopic world! The total magnification can be quite thrilling when you think about the details you're about to uncover! For example, when observing cells or tiny organisms, you're not just seeing shapes, but structures like cell walls or even moving bacteria! Each specimen comes with its own mini drama, and you're the director of this microscopic show. So grab that microscope and get ready for an adventure!
