- . Many galaxies have supermassive black holes at their centers. As material swirls around such a black hole, it is heated, becomes ionized, and generates strong magnetic fields. The resulting magnetic forces steer some of the material into high-speed jets that blast out of the galaxy and into intergalactic space. The light we observe from the jet in Fig. has a frequency of 6.66x10^14 Hz (in the far ultraviolet region of the electromagnetic spectrum), but in the reference frame of the jet material, the light has a frequency of 5.55x10^13 Hz (in the infrared).

- The surface temperature of the naked-eye star Capella (in constellation Auriga) is approximately 4,700 degrees Celsius.a) What is the peak frequency (in hertz) and wavelength (in metres AND nanometres) of Capella’s emitted light?b) If you were to look at Capella in the night sky, what colour would you expect it to appear? Why would you expect this colour?arrow_forwardIf your body temperature is 37°C, then you're giving off the greatest amount of infrared light at a frequency of 3.2x10^13 Hz. Since your cells are mostly water, let's look at one water (H20) molecule, and let's assume that the oxygen atom is mostly staying still, and one of the hydrogen atoms is vibrating at this frequency of 3.2x10^13 Hz (resulting in this infrared radiation). We can model this oscillation as a mass on a spring. A hydrogen atom is just a proton and an electron (and you can ignore the mass of the electron because it's so smnall) a) How much time does it take for the hydrogen atom to go through one full oscillation? b) If you're modeling the hydrogen-oxygen bond as a spring, what is its "spring constant"? c) Our "mass on a spring" has both kinetic energy and potential energy.

These collisions transfer energy to the atmospheric atoms causing them to emit specific colors (wavelengths) of light. On Earth, auroras occur in a layer of the atmosphere known as the ionosphere, 80 km to 400 km above the surface. If solar activity increases, the number of sunspots increases, and more particles are released by the Sun. If, on average, there were 150 sunspots in 2014, 5 in 2020, and 160 in 2023, which year(s) will have the most auroras, and which year(s) the least? Can you explain why? Answer:arrow_forward
