Two point sources produce waves of the same wavelength that are in phase. at a point midway between the sources, what kind of interference would be observed?

What type of light does this light bulb produce most (i.e. at what wavelength does the spectrum have maximum intensity)?

Explain the difference between each pair of concepts. a. frequency and relative frequency b. percentage and relative frequency a. select the correct choice below. a. frequency is the total number of observations in a data set. relative frequency is the number of times a particular distinct value occurs. b. frequency is the number of times a particular distinct value occurs. relative frequency is the ratio of the frequency of a value to the total number of observations. c. frequency is the total number of observations in a data set. relative frequency is the ratio of the number of times a particular distinct value occurs to the frequency. d. frequency is the number of times a particular distinct value occurs. relative frequency is the ratio of the frequency of two different values.

Science and technology are interdependent. advances in one lead to advances in the other. give an example of this phenomenon.
