REAL image is ALWAYS inverted. VIRTUAL image is ALWAYS upright. Convex mirror and diversing lens ALWAYS make negative, virtual, upright image. Is concave lens positive or negative? A concave lens is a diverging lens, so it will always have a negative focal length. Therefore, the power of a...
1求一下三道题的物理答案1.A concave mirror has a focal length of 43 cm. What is the position of the object if the image is erect and is 3 times larger than the object? Answer in units of ___cm.2.An object is placed 5.7 cmin front of a concave mirror with a 28 cm focal lengt...
Concave-convex Lens: What type of image does concave lens produce? Convex (converging) lenses can form either real or virtual images (cases 1 and 2, respectively), whereas concave (diverging) lenses can formonly virtual images(always case 3). Real images are always inverted, but they can be...
1. Understanding Image Formation: - A concave mirror can produce both real and virtual images depending on the position of the object relative to the mirror. - A real image is formed when the object is placed beyond the focal point (F) of the mirror. 2. Identifying Key Points: - The...

Answer to: There is a 12 mm high object that is 10 cm from a concave mirror with a focal length of 17 cm. (a) Where (B) how high, and (C) what type...
An object of size 7.0 cm is placed at 27 cm in front of a concave mirror of focal length 18 cm. At what distance from the mirror should a screen be placed so that a sharp focussed image can be obtained? Find the size and nature of the image.. Ans: H...
Many people should be familiar with the idea of pincushion distortion if they’ve ever looked into a curved mirror, similar to being in one of those carnival ‘funhouses.’ If the mirror is concave (like looking at the inside of a spoon, it bends inward and away from the viewer), the...
