The Human Eye Can Only See Between 430-770 Thz

The human eye can only see

The human eye can only see between 430-770
Our ears can only detect sound between
20Hz-20 Khz.
These ranges make up a fraction of the total
sound and light frequency range.
This means there is so much going around us that
we can neither see or hear.
