E-field Peak Value

AI Thread Summary

The peak value of the electric field (E) in an electromagnetic wave can be calculated using the formula E = cB, where c is the speed of light. Given a magnetic field (B) of 2 x 10^-7 T, the calculation yields E = 60 N/C. The initial query confirms the correctness of this calculation. The response affirms that the calculation is accurate. The discussion effectively clarifies the relationship between the electric and magnetic fields in electromagnetic waves.

Hi,

My Question:

If the peak value of the magnetic field of an EM wave is 2 x 10^-7 T. Calculate the peak value of the E-field.

Work:

C=E/B so,

3*10^8 m/s=(E)/(2*10^-7 T)
(3*10^8 m/s)(2*10^-7 T)=E

E= 60 N/C

Is this right ?

Thank You

Yea that's correct.

E = CB

Thread 'I've come across another fluid pressure problem I don't understand'

Neglect gravity other than that of water; neglect friction. F1=ρgsh=1000*10*1*(1+4)=50000 N; F1=ρgsh=1000*10*0.1*4=4000 N; F3=50000-4000=46000 N?

Thread 'Struggling to understand the concept of this question (ice cube in water optics question)'

TL;DR Summary: I came across this question from a Sri Lankan A-level textbook. Question - An ice cube with a length of 10 cm is immersed in water at 0 °C. An observer observes the ice cube from the water, and it seems to be 7.75 cm long. If the refractive index of water is 4/3, find the height of the ice cube immersed in the water. I could not understand how the apparent height of the ice cube in the water depends on the height of the ice cube immersed in the water. Does anyone have an...

Thread 'Variable mass system : water sprayed into a moving container'

Starting with the mass considerations #m(t)# is mass of water #M_{c}# mass of container and #M(t)# mass of total system $$M(t) = M_{C} + m(t)$$ $$\Rightarrow \frac{dM(t)}{dt} = \frac{dm(t)}{dt}$$ $$P_i = Mv + u \, dm$$ $$P_f = (M + dm)(v + dv)$$ $$\Delta P = M \, dv + (v - u) \, dm$$ $$F = \frac{dP}{dt} = M \frac{dv}{dt} + (v - u) \frac{dm}{dt}$$ $$F = u \frac{dm}{dt} = \rho A u^2$$ from conservation of momentum , the cannon recoils with the same force which it applies. $$\quad \frac{dm}{dt}...
