Chayse is working on analyzing the electromagnetic spectrum, focusing on ultraviolet rays. he determines that a uv ray has a frequency of 1.53 × 1016 hz and a wavelength of 1.96 × 10-8 m. are his results reasonable? explain your answer.

Sample Response: Yes, Chayse's results are reasonable because all parts of the electromagnetic spectrum travel at the speed of light. By multiplying his results for frequency and wavelength, I can see that the velocity of the UV ray is close to the speed of light.

igneous rocks also form where plates converge. the subducting plate melts as it sinks into the crust of the earth, and the melt rises into the overriding plate forming volcanoes. metamorphic rocks are formed mainly in the lithosphere, wherever there is high pressure and high temperature. -woods
