The maximum wavelength that an electromagnetic wave can
haveand still eject electrons from a metal surface is 440 nm. what
is the work functionw0 of this metal? express
your answer inelectrons volts.

Work function will be 2.8125 eV

Explanation:

We have given maximum wavelength that electromagnetic wave emit

Plank's constant

Speed of light  

Work function is equal to

We know that

So

the skeletons of most mammals reach a certain size and then stop growing. however, many animals, including some mammals, keep growing throughout their lives. kangaroos, for example, just keep growing and growing until they die. also, the longer an animal lives the greater the chance it might catch some deadly disease.
