Question

In this module, you will look for an article or news story/video that relates to one or more of the following topics:

Real or virtual images,

Magnification,

Optical interference,

Optical diffraction.

These are pretty broad topics, but a few ideas should spring readily to mind. By the end of the third day of the module, create a thread with a 250-word post including one or more of the topics listed above, an active hyperlink to your resource (this resource cannot be used by another student), a summary of the resource itself, a summary of the material you are learning in this module as it relates to your resource (cite portions of the textbook), and an explanation of how the topic or resource ties to your everyday life. Then provide a substantive reply to at least two of your classmates’ posts (minimum 200 words) before the end of the module. Don’t forget to reply to the comments your classmates leave about your original post, too. Posts made after the posted due date of the discussion will be reviewed by your instructor, but no points will be earned for your effort.

Answer 1

SOLUTION:

OPTICAL INTERFERENCE:

It is the interaction of two or more light waves. Interference is a phenomenon in which two waves superimpose to form a resultant wave. It may have greater, lesser or same amplitude. Interference can be constrctive or destructive. The addition of amplitude of individual waves at each point is affected by more than one wave. If the two waves are of same frequency and phase the wave amplitudes are reinforced, producing constructive interference. If the waves are out of phase by half period the result is destructive interference.
