Chemistry motion of the water’s surface. Similar interference can occur in waves of light. Waves of light refl ected from the inner and outer surfaces of the fi lm of a soap bubble can interfere with each other. Where the crests of the light waves refl ected from the inner and outer surfaces of the fi lm meet, the intensity of the light increases. If the crest of a wave refl ected from the inner surface meets the valley of a wave from the outer surface, the intensity of the light will be diminished. Whether the crest of a wave meets another crest or a valley is determined by the length of the wave and by the thickness of the fi lm. If the thickness of the fi lm is a multiple of the wavelength of the light, the crests of waves refl ected from the inner surface will meet the crests of waves refl ected from the outer surfaces. If the thickness of the fi lm is an odd multiple of half the wavelength, the crests of the waves refl ected from the inner surface will meet the valleys of the waves refl ected from the outer surface. Because the thickness of the fi lm varies and the wavelength of the light determines its color, different areas of the bubble will have different colors. The colors of a fi lm of oil on a wet parking lot are produced in the same way as the colors of a soap bubble. If your soap bubbles remained fl oating on the carbon dioxide for more than a minute, you may have noticed that the bubbles were slowly becoming larger. You also may have noticed that the bubbles slowly sank into the container. Both the growth and the sinking of the bubbles is a result of the same process. When you blew the bubble, it was fi lled with air. When it settled into the container of carbon dioxide, the bubble was surrounded by this gas. The bubble grows because carbon dioxide moves into the bubble (through the soap fi lm) faster than air moves out of the bubble. Carbon dioxide can move through the soap fi lm more quickly than air, because it is more soluble in water than is air. (Water is the major component of the bubble-soap solution.) As the amount of carbon dioxide in the bubble increases, the bubble becomes heavier and sinks lower into the carbon dioxide in which it is fl oating.

Warner Full Name: Isiah Manuel Warner Born: July 20, 1946 Place: DeQuincy, LA Parents: Irma Warner Humphrey Warner Spouse: Della Blount Education: Carver High School - Bunkie, LA (1964) Southern University - Baton Rouge, LA (B.S. Chemistry, 1968) University of Washington - Seattle, WA (Ph.D. Analytical Chemistry, 1977) Type of Science: Chemistry Achievements: Served as the National Science Foundation program offi cer for Analytical and Surface Chemistry Presidential Award for Excellence in Science, Mathematics, and Engineering Mentoring Favorites: Color: Blue Food: Thai Food Quote: “I am Isiah Warner, and I am a country boy from Bunkie, Louisiana.” Time of Year: Autumn Vacation Spot: Europe or Africa Biography Chemistry professor Isiah Manuel Warner was born in DeQuincy, Louisiana, on July 20, 1946. Warner’s parents, Humphrey and Irma Warner, raised him in Bunkie, Louisiana, where at age two, he drank kerosene to determine why it could produce light. Warner graduated as valedictorian from Bunkie’s Carver High School in 1964; attending Southern University on a full scholarship, he graduated cum laude with his B.S. degree in chemistry in 1968. While working as a technician for Battelle Northwest, Warner earned his Ph.D. in analytical chemistry from the University of Washington in 1977. 31
