This is a two part question. Part 1. To look closely at a small object, such as an insect or a crystal, you bring it close to your eye, making the subtended angle and the retinal image as large as possible. But your eye cannot focus sharply on objects that are closer than the near point, so the angular size of an object is greatest when it is placed at the near point (25 cm away from a “normal” eye)....

A microscope objective with a magnification of 19 is used in a microscope with a magnification of 55. Find the focal length of the ocular if the ocular's image is formed at the eye's near point, 26 cm from the eye. Neglect the distance between the eye and the ocular.

A microscope objective with a magnification of 15 is used in a microscope with a magnification of 51. Find the focal length of the ocular if the ocular's image is formed at the eye's near point, 22 cm from the eye. Neglect the distance between the eye and the ocular.

An object 0.90 cm high is viewed under a magnifier of focal length 16 cm by a person with a near point of 28 cm and a far point of ∞. (a) Find the angle subtended by the image formed by the magnifier when the eye is relaxed. (b) Find the angle subtended by the image formed by the magnifier when the eye is focused at its near point.

to anwer Question 4 points
Data provided below
The magnitude of the lateral magnification is defined to be imi = Image Height = 4 Object Height h, 3) From geometry this can be shown to be equal to From ur measurements obtained for source-screen distance equal to 85 cm, compare the yo lateral magnification using each of the two relations above. Do this for the first position o the lens (the unprimed measurements) and then for the second position of...

The generator in the diagram has rms voltage 45 V, at angular frequency omega = 1,000 rad/s. The resistance is R = 3.0 Ohm, and the reactances are X_L = 6.0 Ohm and X_C = 2.0 Ohm. (a) Find L, C the impedance, the rms current, the phase angle by which the voltage lead/lags the current and the average power. L = mH C = mu F Z = I_RMS = phi = plusminus () P_AV = (b) The generator...
