A thin layer of oil (n = 1.38) on the ocean surface for thousands of miles. As an inspector, you are flying over the ocean surface in an aircraft, looking at a section of option where the oil thickness is 563 nanometers thick. You look straight down at the ocean, at a time of day when the sun is directly above you. a) So, if constructive interference occurs (i. e. where the reflection is brightest) what is the wavelength(s) of visible light in the reflection? b) However, in order to get a close-up look at the oil slick, you put on scuba gear and go diving under the portion of ocean you had been observing from the plane. For which wavelength(s) of visible light yield the strongest transmitted intensity?

How do you tell if someone actually cares about you? and just say they do?

Arunner is jogging at a steady 3.6 km/hr. when the runner is 2.9 km from the finish line, a bird begins flying from the runner to the finish line at 14.4 km/hr (4 times as fast as the runner). when the bird reaches the finish line, it turns around and flies back to the runner. even though the bird is a dodo, we will assume that it occupies only one point in space, i.e., a zero-length bird. how far does the bird travel? (b) after this first encounter, the bird then turns around and flies from the runner back to the finish line, turns around again and flies back to the runner. the bird repeats the back and forth trips until the runner reaches the finish line. how far does the bird travel from the beginning? (i.e. include the distance traveled to the first encounter)
