Solutions of thiosulfate are light-sensitive. When exposed to light, they break down into <span>sulfur, sulfite, and sulfate compounds. That is why as much as possible, they must be stored in the dark. This is also the reason why they are stored in amber (dark-colored) bottles.</span>
Answer:- Frequency is
.
Solution:- The wavelength of electromagnetic radiation is given as 625 nm and we are asked to calculate the frequency. Frequency is inversely proportional to the wavelength and the formula used to calculate frequency when wavelength is given is:

where,
is frequency, c is speed of light and
is the wavelength.
Value of speed of light is
. We need to convert the given wavelength from nm to m.

So, 
= 
Let's plug in the values in the formula and calculate the frequency:

=
or Hz.
So, the frequency of the electromagnetic wave is
.
The transition metals are a group of metals that are found in the middle of the periodic table. ... They are also harder than the post transition metals. They make colorful chemical compounds with other elements. Most of them have more than one oxidation state.
