30 POINTS PLEASE HELP ASAP

lina2011 [118]

Hello!

We have the following data:

f (radiation frequency) = $3.0*10^{19}\:Hz$

v (speed of light) = $3.0*10^8\:m/s$

λ (wavelength) = ? (in m)

Let's find the wavelength, let's see:

$f = \dfrac{v}{\lambda}$

$3.0*10^{19} = \dfrac{3.0*10^8}{\lambda}$

$\lambda = \dfrac{3.0*10^8}{3.0*10^{19}}$

$\boxed{\boxed{\lambda = 1*10^{-11}\:m}}\Longleftarrow(wavelenght)\end{array}}\qquad\checkmark$

I Hope this helps, greetings ... DexteR! =)

why does a large lake filled with cool water have more thermal energy than a small pond filled with warmer water

yan [13]

Because the scale is much larger, and a larger pool can collect more energy than a small pool, and it is more likely that it would have more energy spread throughout it.
