Can we see an ideal black body?

    Would an ideal black body be visible to us?

    What about Ferry's black body? How close was it to an ideal black body?

    It depends on it's temperature. In case of a cold black body we would see that we do not see it.

    You can certainly see an ideal black body as long as its temperature is high enough to emit visible light.

    The most common example of an ideal black body is a hole on an oven. The hole absorbs all light and reflects no light (because it is a hole, not a real surface) and the light that comes out is the average temperature of the oven.
