If astronomers look toward any point in outer space, they see radiation that matches the emission spectrum of an object at 2.7 K, a remnant of the Big Bang.
a) What is the peak wavelength of this radiation? (lambda = ?)
b) What part of the electormagnetic spectum is it in?
Radio Region
Microwave Region
Visible Region
Ultraviolet Region
X-Rays Region
Gamma-Rays Region
From the Weins displacemnt law , the peak wave length is
lamda ( peak) T = b
where b is Weins constant
lamda ( peak) = b/T = 2.898 * 10 ^-3 K/2.7 K = 1.07 mm
(b)
micro wave region
