The index of refraction for blue light of wavelength 440 nm in a glass sample is 1.654 and for red light of wavelength 685 nm it is 1.587. If a beam containing these two colors has an angle of incidence with the glass of 30.0°, what is the angle between the two beams inside the glass? Additional Materials O Reading

Which of the following statements are (or could be) true? Choose all that apply. O A glass at a temperature of 43 K will emit EM waves. O The index of refraction of a newly discovered transparent material is 1.6. In a vacuum, radio waves move the same speed as microwaves. O Total internal reflection will occur if the critical angle is greater than the incident angle. A light ray was reflected. The incident angle was 44° and the reflected angle was 60°. O If do = 0, then d; = f.

A goldfish is swimming inside a spherical bowl of water having an index of refraction n = 1.333. Suppose the goldfish is p = 10.7 cm from the wall of a bowl of radius |R| = 19.2 cm, as in the figure below. Neglecting the refraction of light caused by the wall of the bowl, determine the apparent distance of the goldfish from the wall according to an observer outside the bowl.cm behind the glass

The index of refraction n for water is 1.33. What is the speed of light v in water? U = m/s

The index of refraction for blue light of wavelength 434 nm in a glass sample is 1.650 and for red light of wavelength 695 nm it is 1.592. If a beam containing these two colors has an angle of incidence with the glass of 30.0°, what is the angle between the two beams inside the glass? Additional Materials Reading

B1 A light ray leaves a source directed at an angle A = 7 from the vertical. The ray is reflected off of flat surface tilted upwards at an angle of B = 16 from the horizontal. Calculate the angle between the reflected ray and the surface, angle C.
