To determine the focal length of a convex lens, a student focuses a classroom window, a

Answer 1

If we use the sun as a distant object to calculate the convex lens's focal length, we obtain a number that is more closely related to the actual convex lens value.

We need to learn more about a convex lens's focal length in order to locate the solution.

Why, if we concentrate the sun, do we obtain a focal length that is closer to the correct value?

• An optical system's focal length is a measurement of how sharply the light converges or diverges.

• The distance between the convex lens's pole and its focus is known as its focal length.

• Convex lenses focus all of the rays from the distant object at their focal point to create a true image.

• We receive a crisper image if the object is farther away from the lens.

• Away from the focal point, an image will form if we concentrate on a neighboring window.

• To get the focal point on a distant tree, we must move the screen in the direction of the lens.

We can therefore draw the conclusion that if we use the sun as a distant object, we will obtain a value that is closer to the convex lens's actual value.

Answer 2

To determine the focal length of a convex lens, if we are using sun as distant object, then we get a value which is closer to the accurate value of convex lens.

To find the answer, we need to know more about the focal length of a convex lens.

Why we get a focal length which is closer to the accurate value if we focusing sun?

• The focal length of an optical system can be defined as the measure of how sharply it converges or diverges the light.
• Focal length of convex lens is the distance between the pole and the focus of the convex lens.
• Convex lens converges all the rays coming from the distant object at its focal point to form a real image.
• If the object is at more distance from the lens, then we get sharper image.
• If we focus on a nearby window, then image will form away from the focal point.
• In the case of a distant tree, we need to move the screen towards the lens to get the focal point.

Thus, we can conclude that, the if we are using sun as distant object, then we get a value which is closer to the accurate value of convex lens.
