A sheet of glass has and . A narrow beam of white light is incident on the glass at . What is the angular spread of the light inside the glass?
A 2.0-cm-tall object is to the left of a lens with a focal length ofA second lens with a focal length of isto the right of the first lens.
a. Use ray tracing to find the position and height of the image. Do this accurately using a ruler or paper with a grid, then make measurements on your diagram.
b. Calculate the image position and height. Compare with your ray-tracing answers in part a.
An astronomer is trying to observe two distant stars. The stars are marginally resolved when she looks at them through a filter that passes green light with a wavelength near 550 nm. Which of the following actions would improve the resolution? Assume that the resolution is not limited by the atmosphere.
A. Changing the filter to a different wavelength. If so, should she use a shorter or a longer wavelength?
B. Using a telescope with an objective lens of the same diameter but a different focal length. If so, should she select a shorter or a longer focal length?
C. Using a telescope with an objective lens of the same focal length but a different diameter. If so, should she select a larger or a smaller diameter?
D. Using an eyepiece with a different magnification. If so, should she select an eyepiece with more or less magnification?
