An object is placed 10 cm in front of a concave mirror of focal length 5 cm, where does the image form?   a) 20 cm in front of the mirror b) 10 cm in front of the mirror c) 15 cm in behind of the mirror d) 25 cm in behind of the mirror e) at an infinity distance in front of the mirror

The mirror equation relates the object distance, d0, the image distance, di, and the focal length, f, of a mirror as1 / d0 + 1 / di = 1 / fWhile in other topics, distance and length are strictly non-negative, in optics we introduce the following sign conventions: Object distance is positive for a real object and negative for a virtual object. Image distance is positive for a real image and negative for a virtual image. Focal length is positive for a converging mirror and negative for a diverging mirror (a) Select the best choice to complete this statement. A real object placed in front of a converging mirror creates a real image  under all circumstances. under no circumstances. when the object is between the focal point and the mirror. when the object is farther than the focal length from the mirror. (b) Select the best choice to complete this statement. A real object placed in front of a diverging mirror creates a virtual image  under all circumstances. under no circumstances.…

6) An object is placed 20 cm in front of a converging lens of focal length 5 cm, where does the image form?   a) 10 cm in front of the lens b) 6.7 cm in front of the lens c) 10 cm in behind of the lens d) 6.7 cm in behind of the lens e) at an infinity distance in front of the lens

2) When an object is placed 24 cm in front of a mirror, the image is 8 cm behind the mirror. a) Calculate the focal length of the mirror. Professor's Email: Sand Through Campus Mall? Yes/No b) For each of the following two statements, select the correct answer. The image in this problem is A) Real The image in this problem is A) Upright B) Virtual B) Inverted
