It is a continuous exposure. I have also made a mistake, because 0.06J is absorbed only. I got the mass wrong i think. It is supposed to equal 3.85•10-7 Then the change in temperature is about 37K which actually makes sense It's 0.06/(3.85•10-7•4200)

P_b/P_a =0.4 I have calculated mass of the syrup which is 0.42g We know that the power of a laser before is 100mW and after is 40mW, that means that the energy absorbed by the syrup is equal to 0.6J/s. I'm not really sure what to do here, the substance through which laser is going is Maple...

Hello, i just wanted to ask if you can explain to me what thermal lens effect is? I am supposed to answer why laser beam passing through ink or soy sauce creates this effect and i can't find any information on what actually this thermal lens is. I know of course that it is a lens, but why does...
