question 15

Multiple Choice

A diffraction grating of width W produces a deviation $\lambda$ in second order for light of wavelength $\lambda$ . The total number N of slits in the grating is given by:

• A) 2W\(\lambda\)/sin\(\theta\)
• B) (W/\(\lambda\))sin\(\theta\)
• C) \(\lambda\)W/2sin\(\theta\)
• D) (W/2\(\lambda\))sin\(\theta\)
• E) 2\(\lambda\)/sin\(\theta\)

Definitions:

Coefficient Of Correlation

An evaluative score indicating the intensity and directional path of a linear connection between two factors.

Variation

Variation refers to the degree to which data points in a dataset or population differ from each other and from the mean.

Dependent Variable

In an experiment or study, it is the variable that is being tested and measured, expected to change in response to alterations in the independent variable.

Coefficient Of Correlation

A statistical measure that quantifies the degree to which two variables change together; ranging from -1 to 1.
