How do you find the image distance of a convex lens?
Procedure
- Place the convex lens on a lens holder, placing the screen on the other side of the lens.
- Try focusing the image to get a sharp, clear and inverted image on the screen.
- The position at which the lens is fixed, mark it as O.
- Once the focal length is calculated, mark point F on both the sides of the lens.
How do you calculate the distance from the lens to the image?
- To calculate the image distance, the lens formula can be used.
- 1/u+1/v=1/f.
- where.
- u is the object distance.
- v is the image distance.
- f is the focal length of the lens.
- If you know the focal length and object distance, using the above formula image distance can be calculated.
How do you solve a convex mirror equation?
Suppose an object is placed u cm in front of a spherical mirror of focal length f such that the image is formed v cm from the mirror, then u, v and f are related by the equation; 1/f= 1/u + 1/v. This equation is referred to as the mirror formula. The formula holds for both concave and convex mirrors.
How does a convex lens form an image?
A convex lens forms an image by refracting light rays. Light rays reflected from an object are refracted when they enter the lens and again when they leave the lens. They meet to form the image.
How will a convex lens change the image of an object?
A convex lens is thicker in the middle than at the edges. This causes rays of light to converge. The light forms a real or virtual image depending on the distance of the object from the lens.
HOW IS lens working distance calculated?
Lens calculator – Calculating the working distance a
- classic. a= f´* (y /y´ +1)
- using sensor information.
- using object size. & opening angle.
Can a convex mirror form a real image?
Yes,convex mirror can form real image when the convergent rays are incident on the mirror. when convergent rays are incident yo convex mirror then the reflected rays intersect at a point in same side of mirror or in front of mirror and form real image.
Under what condition the convex lens forms a real image?
A convex lens forms a real image on a screen when an object is placed at 10 cm from the screen. On shifting the lens by 2 cm, a real image is again formed on the screen. Find the focal length of the lens.
