Exercise 2: A large space telescope (Planck) measured a faint source of microwave radiation, which seemed to come from all directions in the sky at once. The signal was fairly strong, accounting for approximately 1% of all he static noise" that can be detected by any television antenna. This emission signal is represented by the graph on the right. It shows the brightness of the microwave emission (on the y-axis] vs. wavelength (on the x-axis. Note: you do NOT need to know the actual value that he peak emission reaches on the y-axis, which is why there are no numbers on the y-axis. You ONLY need to In find the wavelength (x-axis] that approximately corresponds with the location of the peak. WAVELENGTH 1.5 points) Using Wien's law (Equation 1) and using the peak wavelength indicated on the graph (and remember to convert the wavelength you find to nanometers) calculate the temperature for this microwave emission. Look up what this temperature physically represents in the Universe! I=0.289k
