Using infrared (IR) light waves instead of Bluetooth for a home remote controller makes sense. Make a strong case for your position by providing solid evidence to back it up.
Why can’t we see stars in the daytime?
Does one of these visible light waves move faster than the others? Which one is fastest and why?
I need help because I think it is wave C but I am not confident. Thanks

- Imagine that a spacecraft has landed on Mercury and is transmitting radio signals to Earth at a wavelength of 10.000 cm. When Mercury is seen from Earth in the evening sky, at its greatest angular distance east of the Sun, it is moving toward Earth at its maximum possible relative speed of 47.9 km/s. To what wavelength must you tune your radio telescope to detect the signals? (Hint: Use the Doppler formula in Reasoning with Numbers 6-2.)arrow_forwardAs light travels from air into water, what happens to the frequency of the light? Consider how the wavelength and speed of light change; then use the relationship between speed, wavelength, and frequency for a wave. What about light that is reflected off the surface of water? What happens to its wavelength, speed, and frequency?arrow_forwardwhat is the answer to the first and last question?arrow_forward
