Cold water surrounds Australia and warm water surrounds Southern America. Wind currents from the two continents flow towards each other and meet near the island of Tahiti. Consequently, the air is pushed upwards. a) What does this mean for the moisture in the wind? b) what is the climate effect on Australia’s north east? ric00121 https://padlet.com/ric00121/47jng165a1pw/wish/336705492 2019-03-01 01:27:50 UTC https://padlet.com/ric00121/47jng165a1pw/wish/336705492 Wein's Law https://padlet.com/ric00121/47jng165a1pw/wish/336706074  A probe in Earth's orbit is studying the Earth's magnetic field. During the journey, the probe's peak surface temperature is 126 degrees celsius, and its lowest surface temperature is -270 degrees celsius.

a) What is the peak wavelength emitted by the probe?
b) What is the lowest wavelength emitted by the probe?
c) If the visible spectrum of light is between 400-700nm, will the probe ever emit visible light?
