What does a convex lens do to an image?
A convex lens converges light rays to a focal point, which creates a real and inverted image if the object is placed beyond the focal length. If the object is placed within the focal length, a virtual and upright image is formed.
When does a convex lens forms a real or virtual image?
When object is within the focal distance then virtual image is formed. But when the object is placed beyond the focus of the covex lens ie if the distance of the object is more than focal length then real image is formed.
When does a Convex lens form a virtual or real image?
When object is within the focal distance then virtual image is formed. But when the object is placed beyond the focus of the covex lens ie if the distance of the object is more than focal length then real image is formed.
What does the image formed by convex lens depend upon?
The image formed by a convex lens depends on the object distance from the lens, the focal length of the lens, and the object size. These factors determine whether the image formed is real or virtual, magnified or diminished, and upright or inverted.
If an object is closer to a convex lens than one focal length the image is .?
If an object lies within the focal length of a convex lens, its image will be erect, bigger in size and virtual. It will be on the same side of the object.
What are the two possibilities for an image formed by a convex lens?
Convex (I prefer converging lenses) lenses are thicker in the middle than at the edges. This causes the rays to converge towards the principle axis (line running through the center of the lens perpendicular to the surface). two images will be formed. When the object you are viewing is farther from the lens than the focal length you will have an inverted real image. This image can be enlarged (when the object is between the focal length and twice the focal length), the same size (when the object is twice the focal length from the lens) or reduced (when the object is beyond twice the focal length). When the object is closer to the lens than the focal length you are using the lense as a magnifying glass and you will have an upright virtual image.
What determines an objects position relative to whether a convex lens forms a real or virtual image?
The position of the object relative to the focal point of the convex lens determines whether a real or virtual image is formed. If the object is beyond twice the focal length of the lens, a real inverted image is formed. If the object is within twice the focal length, a virtual upright image is formed.
How do you derive relation between focal length and radius of curvature of convex mirror?
For a convex mirror, the focal length (f) is half the radius of curvature (R) of the mirror. This relationship arises from the mirror formula for convex mirrors: 1/f = 1/R + 1/v, where v is the image distance. When the object is at infinity, the image is formed at the focal point, and the image distance is equal to the focal length. Hence, 1/f = -1/R when solving for the focal length in terms of the radius of curvature for a convex mirror.
What is the nature of image formed by a convex lens?
A convex lens forms a real or virtual, inverted or upright image, depending on the object distance and the focal length of the lens. The image can be either magnified or reduced in size compared to the object.
An object is placed at a distance of 50 cms from a convex lens of focal length 20cms then find the nature and position of the image?
Since the object is placed beyond the focal length of the convex lens (50 cm > 20 cm), the image will be real, inverted, and formed between the focal point and twice the focal length on the opposite side of the lens. The position of the image can be calculated using the lens formula: 1/f = 1/v - 1/u, where f is the focal length of the lens, v is the image distance, and u is the object distance.
When object is positioned at more than twice the focal length of a convex lens what are the properties of its image?
When the object is positioned at more than twice the focal length of a convex lens, the image formed is real, inverted, and smaller in size. The image is formed between the focal point and the optical center of the lens.
What is a focal point in convex lens?
A focal point in a convex lens is the point where parallel rays of light converge after passing through the lens. It is located on the principal axis of the lens at a specific distance from the lens center, known as the focal length. This focal point is where an image is formed when an object is placed at an appropriate distance from the lens.
