Magnifying power of simple microscope can be increased by?
Increasing the focal length of the lens or using a lens with a shorter focal length can increase the magnifying power of a simple microscope. Using a lens with a higher refractive index can also enhance the magnification. Additionally, increasing the distance between the lens and the object being observed can improve the magnification.
What is the magnifying power?
The magnifying power refers to how many times larger an object appears when viewed through a magnifying lens or instrument. It is calculated by dividing the focal length of the lens by the focal length when the object is at the near point of distinct vision (25 cm). This ratio determines the magnification level of the lens.
Why is convex lens of small focal-length preferred for magnifying glass?
A convex lens with a small focal length has a greater magnifying power, allowing it to produce a larger and clearer image when used as a magnifying glass. This is because the shorter focal length allows the lens to bend light rays more sharply, resulting in a more pronounced magnification effect.
What determines the characteristics of images seen through a magnifying glass?
The characteristics of images seen through a magnifying glass are determined by the magnification power of the lens, the distance between the lens and the object being viewed, and the focal length of the lens. These factors affect the size, clarity, and distortion of the image.
Which lens has a greater power convex lens of focal length 10 cm or a convex lens of focal length 20cm?
Power is inversely related to the focal length. So convex lens of focal length 20 cm has less power compared to that having focal length 10 cm
What is the magnifing power of the lens?
Depends on your microscope. We've got one that's a x2.

What is a positive lens the same as?
A positive lens is also called a magnifying lens. It has convex surfaces and it has a measureable focal length where it produces an inverted image of a distant object. The power in dioptres is the reciprocal of the focal length in metres.
What is the power of 2 m focal lens?
The power of a lens is calculated as the reciprocal of its focal length in meters. Therefore, a 2 m focal length lens would have a power of 0.5 diopters.
What is the power of a convex lens with 10cm focal length?
The power of a lens is calculated as the reciprocal of its focal length in meters. Therefore, a convex lens with a 10 cm focal length has a power of +10 diopters.
Which lens provides more magnification-a low power or a high power?
A lens of short focal length has a greater power (than a lens of large focal length)
How are images produced by the convex lens of a magnifying glass are affected by focal length?
The focal length of a convex lens determines the magnification of the image produced by the magnifying glass. A shorter focal length will result in a larger magnification, making the image appear bigger. Conversely, a longer focal length will result in a smaller magnification, making the image appear smaller.
What is the power of a lens of focal length 40cm?
The power of a lens is given by the formula P = 1/f, where f is the focal length of the lens. Therefore, for a lens with a focal length of 40cm, the power would be P = 1/40 cm = 0.025 diopters.
