Explanation:
It is known that relation between wavelength and frequency is as follows.
where, = wavelength
c = speed of light =
[/tex]\nu[/tex] = frequency
It is given that frequency is . Hence, putting this value into the above formula and calculate the wavelength as follows.
=
or, =
Thus, we can conclude that wavelength of given radiation is .
Explanation:
Lead can cause effects on the blood, as well as the nervous, immune, renal and cardiovascular systems. ... Exposure to high amounts of lead can cause gastrointestinal symptoms, severely damage the brain and kidneys, and may cause reproductive effects. Large doses of some lead compounds have caused cancer in lab animals.
I can't see the pictures clearly but maybe this will help
