Can cosmic background radiation be seen?
Ariana AcostaCosmic micro wave back ground radiation is in the form of micro waves.
Such low power radiation, which corresponds to 2.7 degrees K, can only be measured by sensitive equipment; it is not in the visible spectrum.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
