All objects emit ______ radiation.
Is it incident?
The frequency of the radiation of most objects is
a) below
b) in the middle of
c) greater
than he frequency of the visibile light spectrum?
I think its below as most objects can not be seen by visible light.
Many words could be fill that blank. One would be "some". Others would be "incoherent", "far infrared", "millimiter wave", "microwave" and "less than or equal to black body"
The radiation frequency emitted by most objects (at normal temperatures)is below the visible light frequencies. Your answer is correct.
All objects emit electromagnetic radiation.
To answer the second question, we need to understand the concept of black body radiation and the electromagnetic spectrum. Black body radiation states that all objects above absolute zero temperature emit electromagnetic radiation. This radiation is distributed across a range of frequencies, including the visible light spectrum.
However, the frequency of the radiation emitted by most objects is below the frequency of the visible light spectrum. This is because the visible light spectrum covers a small range of frequencies within the larger electromagnetic spectrum. Most objects emit radiation in the infrared range, which has frequencies below those of visible light.
Therefore, your observation is correct. The frequency of radiation emitted by most objects is below the frequency of the visible light spectrum.
