A Single Slit Forms a Diffraction Pattern,with the First Minimum

question 6

Multiple Choice

A single slit forms a diffraction pattern,with the first minimum at an angle of 40.0° from central maximum,when monochromatic light of 630-nm wavelength is used.The same slit,illuminated by a new monochromatic light source,produces a diffraction pattern with the second minimum at a 60.0° angle from the central maximum.What is the wavelength of this new light?

• A) 425 nm
• B) 450 nm
• C) 475 nm
• D) 500 nm
• E) 525 nm

Definitions:

Concentration Gradient

A variation in the concentration of a substance across a distance, leading to the movement of particles from an area of high concentration to one of lower concentration.

Carrier Molecules

Proteins that facilitate the transport of substances across a cell membrane without modification of the transported substance.

Facilitated Diffusion

A transport process where molecules pass across cell membranes through protein channels without the expenditure of cellular energy.

Active Transport

The movement of substances across cell membranes against a concentration gradient, requiring energy expenditure by the cell.
