Many expressions in special relativity contain the gamma (y) factor. 1 Y = v²lc² In the equation, v is the speed of some object or reference frame and c is the speed of light. Find the numerical value of y for each of the listed speeds. v = 0, Y = v = 0.550c, v = 0.980c, Y =

Two plane mirrors are at an angle of ?1 = 64.5° with each other as in the side view shown in the figure below. If a horizontal ray is incident on mirror 1, at what angle ?2 does the outgoing reflected ray make with the surface of mirror 2?

Answer it correctly please

Consider the diagram showing a light ray reflecting off a plane mirror. If angle B were 47°, then the angle of reflection (angle C) would be Z D

An object is placed 12 cm in front of a concave mirror of radius 40 cm. Find the position and magnification of the image. State whether the image is real or virtual, and draw a light ray diagram to show the image.

An object is placed in front of a concave mirror with a 20-cm focal length. What is the position of the resulting image (in cm) if the image is inverted and three times larger than the object? Where is the position of object?

If you have a mirror that curved in the opposite direction, then the one that is in #4 (in the image attached) Will the focal length be the same for this mirror as it is in #4? It will still be negative It will now be positive It is hard to know at this time It will not have a focal length   Describe what this mirror looks like in the space below Now draw that mirror       Go back up to part n and do the following steps: Draw the ray that will only head to the vertex. MAKE SURE TO LABLE THIS RAY AS #1 Now depending on where you put the vertical arrow, draw the ray that goes thru the focal point Can you see where this image will form? Yes No   Circle all that apply… From the notes and the lecture, the image formed will be: On the same side as the object On the opposite side of the mirror It will depend on the object’s location   Is this image located: Behind the focal point In front of the focal point At the center of curvature Behind the center of curvature Between the…

Two plane mirrors are at an angle of 0, = 65.6° with each other as in the side view shown in the figure below. If a horizontal ray is incident on mirror 1, at what angle 0, does the outgoing reflected ray make with the surface of mirror 2? Mirror 1 Mirror 2

Hello, I need help with questions #6 and #7. Thank you!

Figure 5 shows a double concave lens, and an object is placed at the point O. The focal points of this lens are at the points F and F', and the center of the lens is at the point C. Draw the image of this object. F' A Figure 5: F
