NettetIntensity formula is, I=25×10 3 /35×10 6 =7.14×10 -2 W/m 2 Problem 2: Calculate the power of a wave whose intensity and area of the cross-section are 30×10 -5 W/m 2 and 50m 2 respectively? Answer: Known quantities are, I = 30×10 -5 W/m 2 and A = 50m 2 Intensity formula is, P= I x A P = 30 x 10 -5 x 50 P= 0.015W
NettetFrom Equation 16.31, the intensity of the laser beam is I = 1 2cε0E20. The amplitude of the electric field is therefore E0 = √ 2 cε0I = √ 2 (3.00 × 108m/s)(8.85 × 10−12F/m)(1.0 × 10−3W/m2) = 0.87V/m. The amplitude of the magnetic field can be obtained from Equation 16.20: B0 = E0 c = 2.9 × 10−9T. Example 16.4 Light Bulb Fields NettetIntensity of a wave is the average rate of energy transfer per unit area perpendicular to the direction of the propagation of the wave. It's the same as the average power of the wave per unit area. You can see in Figure 2 that a sound source emits sound waves in three dimensional space. The imaginary spherical surfaces of radius r1 r 1 and r2 r ...
NettetThe average intensity of an electromagnetic wave I ave can also be expressed in terms of the magnetic field strength by using the relationship B = E / c, and the fact that ε 0 = 1 / μ 0 c 2, where μ 0 is the permeability of free space. Algebraic manipulation produces the relationship I ave = cB 0 2 2μ 0, 24.19 Nettet9. apr. 2024 · The intensity is generally defined as the amount of energy that is crossing per unit area per unit time that is perpendicular to the direction with respect to the propagation of the wave. Intensity is measured in the W m –2. Types of Progressive waves . Progressive waves are also known as traveling waves. It reveals continuously.
