V. G. Veseago, a physicist of USSR, issued a new idea of left hand materials for the first time in 1968. Because both the permittivity and permeability of the material are negative, the refravtion index is also negative from the law n = √ε√μ. If a light incident from the vacuum at an angle of 30 to the above material with refraction index of λ= -1.5, please draw the direction in the material. Does the total refraction effect exist in this materials when the light incident from large angles? (note Snell's Law) (12%) 2. A physicist always runs the red light. However he argues that because the speed of his car is too high, the red (λ = 700 nm) light becomes green light (λ = 550 nm). What is the speed if the phenomena do happen? What is the wavelength the green light becomes at the speed of 0.5c. (12%) 3. Explain the followings. (a) What is the photoelectric effect? Give a least one example of application by this effect. (b) What is Lorentz transformation? (c) What is time dialation? (20%) 4. Light of wavelength 440 nm passes through a double slit, yielding a diffraction patern whose graph intensity I versus angular position is shown in figure 2. Calculate (a) the slit width (b) the slit separation (c) Verify the displlayed intensities of the m = 1 and m = 2 interference fringes. (20%) 5. Write down the Maxwell equations and explain the meaning of each equation in detail. (12%) 6. A RLC circuit is shown in Fig. 3 (a) derive the differential equation of this circuit that is analogue to te mechanical damping waution mx'' + bx' +kx = Fcosωt (b) What is the frequency of the system afer time is sufficiently long? (c) What is the resonant frequency if the resistance R is negligible? (24%) 7. Write down your points of view, comments, feeling etc about this course, homework, quiz, exam, professor Huang, T.A. and so on. (10%) --
