The type of image produced by the objective lens in a refracting telescope.

Explanation of Solution
Introduction:
Refracting telescope is an optical telescope in which lens is used as its objective to form an image of an object under observation. Objective lens bends the light rays that are parallel to the optic axis of the lens and focuses them in to a focal point.
Refracting telescope is composed of two lenses. Objective lens is the first lens. This forms the real and inverted image inside the focal length of eyepiece, which is the second lens. The real image produced by an objective lens acts as an object for the second lens (eyepiece). Eyepiece produces a virtual and magnified image that can be seen by an observer.

- The rectangular loop of wire shown in the figure (Figure 1) has a mass of 0.18 g per centimeter of length and is pivoted about side ab on a frictionless axis. The current in the wire is 8.5 A in the direction shown. Find the magnitude of the magnetic field parallel to the y-axis that will cause the loop to swing up until its plane makes an angle of 30.0 ∘ with the yz-plane. The answer is .028 T, I just need help understanding how to do it. Please show all steps.arrow_forwardA ray of light from an object you want to look at strikes a mirror so that the light ray makes a 32 degree angle relative to the normal line (a line perpendicular to the surface of the mirror at the point where the ray strikes the mirror). If you want to see the object in the mirror, what angle does your line of sight need to make relative to the normal line? Give your answer as the number of degrees.arrow_forwardSuppose you have a converging lens with a focal length of 65 cm. You hold this lens 120 cm away from a candle. How far behind the lens should you place a notecard if you want to form a clear image of the candle, on the card? Give your answer as the number of centimeters.arrow_forward
- Suppose you have a diverging lens with a focal length of - 25 cm. You look through this lens at a sleeping squirrel, and notice that it forms a virtual image of the squirrel with di = - 18 cm. How far away from the lens is the squirrel? Give your answer as the number of centimeters (a positive number).arrow_forwardDiamond has an index of refraction of about 2.4. Suppose you cut a diamond so it has a flat surface, and shine a laser pointer beam so that it makes a 27 degree angle with respect to the normal line to that surface. What angle will the laser beam make with respect to the normal after it passes through the air-diamond boundary and is inside the diamond? Give your answer as the number of degrees.arrow_forwardFind current of each line of D,E, and F. Where V1 is 9V, V2 is 7V, R1 is 989 , R2 is 2160, R3 is 4630 , R4 is 5530, R5 is 6720, and E is 16V.

- You are tasked with designing a parallel-plate capacitor using two square metal plates, eachwith an area of 0.5 m², separated by a 0.1 mm thick layer of air. However, to increase the capacitance,you decide to insert a dielectric material with a dielectric constant κ = 3.0 between the plates. Describewhat happens (and why) to the E field between the plates when the dielectric is added in place of theair.arrow_forwardCalculate the work required to assemble a uniform charge Q on a thin spherical shell of radiusR.
