What can be determined about the wavelength of the light from the star? A) The light is blue shifted. B) The light is red shifted. C) The wavelength of the light is not changed. D) None of the other answers is correct. n3 n2 ni 30° 3. A light ray travels from medium 1 to medium 2 to medium 3 as shown to the right. For these media: 40° B) n3> n D) Cannot compare ni and ns without knowing n2 Which of these forms of electromagnetic radiation carries the least energy? 4.

F)X-rays E) visible light D) ultraviolet B) microwaveC) radio wave A) infrared 6. The equation: nisinvi 5 n2sinv2, is known as which law? A) Maxwell's B) Polarization C) Reflection D) Snell's E) Young's 7. Which of the rays labeled in the diagram to the right would likely correspond to visible light that is indigo ? A) B) C) D) E) F) G)

Answer 1

1-C - in transverse wave particles oscillates perpendicular to the direction of motion.

2-B- friquency is increased Hance the light is red shifted.

3-B- the ray is much deviated toward axis in n3 so n3 must be higher than n1.

4-radio waves have the least energy.
