What is the nature of an image formed by a concave mirror of focal length 10 cm for a real object placed 3 cm from the mirror
real and inverted
real and upright
virtual and inverted
virtual and upright
Would it be virtual and inverted, I do not believe that it could be real so that would take out the first 2 choices and upright wouldnt work for concave?
You are correct. The image formed by a concave mirror with a focal length of 10 cm for a real object placed 3 cm from the mirror is virtual and inverted. To understand why, let me explain the concept.
When an object is placed in front of a concave mirror, the mirror reflects the light rays and forms an image. The nature of the image can be determined by considering the position of the object with respect to the focal point of the mirror.
In this case, the object is placed at a distance of 3 cm from the mirror, which is less than the focal length of 10 cm. When the object is located within the focal length of a concave mirror, the mirror forms a virtual image. This means that the light rays do not actually converge to a point where the image appears to be located.
Furthermore, the image formed by a concave mirror when the object is located within the focal length is always inverted. This means that the top and bottom of the object are flipped in the image. So, the correct answer is virtual and inverted.
Almost.
