4. Spectra and filtering. a. White light has an approximately constant spectrum in the visible range from 400-700nm, with a constant intensity of, say, I = 100W/m2. Draw a picture of this spectrum over the visible range; make sure to label your axes (intensity vs wavelength). %3D b. Suppose the light is passed through a green filter; this filter transmits 10% of the intensity for frequencies outside the green range 500-570nm and 90% of the intensity in the green Tange Draw the spectrum of the filtered light.

Fluid Kinematics

The branch of science that deals with objects which are either in motion or stationary are studied under the branch of classical mechanics. Fluid mechanics is a subcategory of classical mechanics that deals with the behavior of fluids at rest (fluid statics) or in motion (posing some velocity). In fluid kinematics, studies focus on the associated motion of fluid particles or groups of particles, and its associated parameters like displacements, velocity, and acceleration without concerning about the forces that caused the motion. All the laws of classical mechanics are applied in the study of fluid kinematics.
