a.) use the lens equation to calculate the image distance.
b.) sketch a scaled ray diagram and show the location of the iamge using 3 principle rays.
c.) calculate the magnification of the object.
d.) state wether the mage is real or cirtual and explain how you know.
When you irradiate a metal with light of wavelength 435 nm in an investigation of the photoelectric effect, Find the work function of the irradiated metal in electron volts
A woman throws a ball at a vertical wall d = 3.0 m away. The ball is h = 1.5 m above ground when it leaves the woman's hand with an initial velocity of 12 m/s at 45°.
Suppose a car is traveling at 14 m/s, and the driver sees a traffic light turn red. After 0.50 s has elapsed (the reaction time) the driver applies the brakes and the car decelerates at 8.0 m/s2.
Two balls of mass 0.6 kg and 0.8 kg are connected by a low-mass spring. This device is thrown through the air with low speed, what is the total momentum of the device
Coherent light with wavelength 546 nm passes through two very narrow slits, and the interference pattern is observed on a screen the distance of 3.00 {rm m} from the slits. The first-order bright fringe is a distance of 4.86 {rm mm} from the center o..
This question requires two answers. A hollow metal sphere carries a charge of 5.0 μC. How much charge is on the larger sphere
Two golf balls are glued together and rotated about an axis through the point where they are joined. What is the moment of inertia of the pair of golf balls around the chosen axis
Two converging lenses are separated by 23.20 cm. The focal length of each lens is 12.20 cm. Determine the final image distance relative to the lens on the right
A ray of light is incident on the surface of a block of clear ice at an angle of 35.0 degrees with the normal. Find the angle between the reflected and refracted angle
Find out the magnitude of the friction force acting on the case. Laser light with a wavelength = 680 illuminates a pair of slits at normal incidence. What slit separation would produce first-order maxima at angles of 40 from the incident direction.
Suppose you hear a clap of thunder 15.80 s after seeing the associated lightning stroke. The speed of sound waves in air is 343-m/s, and the speed of light in air is 3.00x 10^8 m/s.
school yard teeter-totter with a total length of 5.50 and a mass of 36.00 is pivoted at its center. A 19 child sits on one end of the teeter-totter. Where should a parent push vertically downward with a force of 250 in order to hold the teeter-tot..
