Get started for freeAn object initially at infinity is brought closer to a converging lens. As the object is moved, (A) the inverted image moves closer to the far focus and becomes larger. (B) the inverted image moves farther out from the far focus and becomes larger. (C) the upright image moves closer to the far focus and becomes larger. (D) the upright image moves farther out from the far focus and becomes larger. (E) the inverted image moves farther out from the far focus and becomes smaller.
A beam of light in water \(\left(n_1=4 / 3\right)\) strikes an interface with a piece of glass \(\left(n_2=1.5\right)\). The critical angle at which total internal reflection takes place is (A) \(0^{\circ}\) (B) \(48.6^{\circ}\) (C) \(62.7^{\circ}\) (D) \(90^{\circ}\) (E) Total internal reflection cannot take place
An object initially at infinity is brought closer to the focus of a concave mirror. As the object moves in, (A) the inverted image moves closer to the focus and becomes larger. (B) the inverted image moves farther out from the focus and becomes larger. (C) the upright image moves closer to the focus and becomes larger. (D) the upright image gets farther out from the focus and becomes larger. (E) the inverted image gets farther from the focus and becomes smaller.
As in the previous problem, an object initially at infinity is brought through the focus of a concave mirror. As the object is moved, (A) a real, inverted image becomes an upright, virtual image on the object side of the mirror. (B) a real, inverted image becomes an upright, real image on the object side of the mirror. (C) an upright, virtual image on the object side of the mirror becomes an upright, virtual image behind the mirror. (D) a virtual, inverted image on the object side of the mirror becomes an upright, virtual image behind the mirror. (E) a real, inverted image becomes an upright, virtual image and appears behind the mirror.
A beam of parallel light rays is incident on an opaque screen that has a large opening in it. The opening is fitted with clamps designed to hold optical devices. If you want to produce a tiny spot of light on a distant wall, you should place in the clamps which of the following devices? (A) A prism (B) A narrow slit in a piece of cardboard (C) A rectangular piece of glass (D) A converging lens (E) A diverging lens
