... such as diffraction, light is thought of as a wave, the details of which you will study in higher classes. Again, at the beginning of the 20th century, it became known that the wave theory of light often becomes inadequate for treatment of the interaction of light with matter, and light often behave ...

Hard to tell if there is strong magnification present from current data. Statistical properties of high-z radio quasars may be more useful in determining importance ...

... Each Magellanic Cloud is trailing a long stream of cold atomic gas known as the Magellanic Stream, which stretches around the Sky, observable only in the radio wavebands. The SMC is particularly affected, being the lower mass the two, and suffering from the combined force of the LMC as well as the M ...
