Water Waves Approach an Aperture

question 27

Multiple Choice

Water waves approach an aperture.The resulting patterns are shown for two different cases,A and B,in which the wavelength and aperture size are varied. Which one of the following statements concerning these cases is true?

• A)Neither figure shows diffraction.In both cases,the wavelength is much smaller than the aperture.
• B)Diffraction occurs in A,but not in B because the wavelength in A is much smaller than the aperture.
• C)Diffraction occurs in B,but not in A because the wavelength in B is much smaller than the aperture.
• D)Both figures show diffraction.In both cases,the wavelengths are approximately the same size as the aperture.
• E)Diffraction occurs in B,but not in A because the wavelength in B is approximately the same size as the aperture.

Definitions:

Cori Cycle

Named for Czech-U.S. biochemist and Nobel laureate Carl F. Cori (1896–1984). Lactic acid, produced by skeletal muscle, is carried in the blood to the liver, where it is aerobically converted into glucose. The glucose may return through the blood to skeletal muscle or may be stored as glycogen in the liver.

Protein Metabolism

The process by which proteins are synthesized, broken down, and converted into other proteins or forms of energy within the body.

Ammonia

A colorless gas with a distinct, pungent smell, NH3, used in various industrial processes and also produced as a waste product in organisms.

Urea

A nitrogenous compound produced in the liver as a waste product of protein metabolism and excreted in urine.
