When the laser intensity approaches saturation, the fluorescence from the upper Where (E,)i is the spectral irradiance of level i (W m2 nm-1) and ni and nj are the Substituting fluorescence power yield equation 2.4 and 2.17 into 2.16 and of ten grams of water, placed in the digestion vessel inside the microwave oven, 0.120 m. Explanation: What you need to know here is that frequency and wavelength have an inverse relationship as described by the equation. "0.120 m" What you need to know here is that frequency and wavelength have an inverse relationship as described by the equation color(blue)(|bar(ul(color(white)(a/a)nu * lamda = c color(white)(a/a)|))) Here nu - the frequency of the electromagnetic wave lamda - its wavelength c - the speed of light in a vaccuum, usually given as 3 * 10^8"m s"^(-1) In your case, the frequency of the wave is said to be equal to "2.50 GHz". Now, hertz is defined as one cycle per second. Your electromagnetic wave has a frequency of 2.50 color(red)(cancel(color(black)("GHz"))) * (10^9"Hz")/(1color(red)(cancel(color(black)("GHz")))) = 2.50 * 10^9"Hz" which means that in one second it covers 2.50 * 10^9 complete cycles. You can thus rewrite the given frequency as nu = 2.50 * 10^9"s"^(-1) Rearrange the above equation to solve for lamda nu * lamda = c implies lamda = c/(nu) Plug in your value to find lamda = (3 * 10^8"m" color(red)(cancel(color(black)("s"^(-1)))))/(2.50 * 10^9color(red)(cancel(color(black)("s"^(-1))))) = color(green)(Calculate the total charge on all electrons in 3.0 g of copper and compare 32 μ C to (8.99 × 109 N ⋅ m 2 /C2 )(4.2 × 10−30 C ⋅ m) cos 0 (2.4 × 10 Only 75% of the heat from the oven is used to heat the water. 1 kg ⎞ (0.120 L) ⎜ ⎟ (4186 J/kg ⋅ C°)(85 C°) ⎝ 1L ⎠ = 23.46 s ≈ 23 s 0.65(2800 W).

What you wish to have to know here is that frequency and wavelength have an inverse relationship as described by means of the equation
#color(blue)(|bar(ul(colour(white)(a/a)nu * lamda = c color(white)(a/a)|)))#
Here
#nu# - the frequency of the electromagnetic wave#lamda# - its wavelength#c# - the velocity of mild in a vaccuum, in most cases given as #3 * 10^8"m s"^(-1)#
In your case, the frequency of the wave is said to be equal to #"2.50 GHz"#. Now, hertz is defined as one cycle consistent with 2d. Your electromagnetic wave has a frequency of
#2.50 color(red)(cancel(color(black)("GHz"))) * (10^9"Hz")/(1color(crimson)(cancel(colour(black)("GHz")))) = 2.50 * 10^9"Hz"#
which means that that in one 2d it covers #2.50 * 10^9# entire cycles. You can thus rewrite the given frequency as
#nu = 2.50 * 10^9"s"^(-1)#
Rearrange the above equation to unravel for #lamda#
#nu * lamda = c implies lamda = c/(nu)#
Plug for your value to find
#lamda = (3 * 10^8"m" colour(purple)(cancel(color(black)("s"^(-1)))))/(2.50 * 10^9color(purple)(cancel(colour(black)("s"^(-1))))) = color(green)(|bar(ul(color(white)(a/a)color(black)("0.120 m")color(white)(a/a)|)))#
The solution is rounded to a few sig figs, the number of sig figs you might have for the frequency of the electromagnetic wave.
