Light has a wavelength of 310.3 nm and a frequency of 5.683 × 10¹4 Hz when traveling through a certain substance. What is the refraction index of this medium? Use 2.998 × 108 m/s for the speed of light in a vacuum. Number i Units

1. A light ray hits a surface at an angle of 12°. The material on the other side of the surface has an index of refraction of 1.14 and the light is making an angle of 15° with the surface when it exits on the side. What is the index of refraction on the incident side of the surface?

A laser beam shines along the surface of a block of transparent material. (See the figure .) Half of the beam goes straight to a detector, while the other half travels through the block and then hits the detector. The time delay between the arrival of the two light beams at the detector is 6.10 ns. Part A What is the index of refraction of this material? n = -- ΑΣΦ Submit Request Answer ? n = ? -2.50 m- Detector

A flat sheet of ice (n = 1.309) has a thickness of 2.7 cm. It is on top of a flat sheet of crystalline quartz (n = 1.544) that has a thickness of 1.5 cm. Light strikes the ice perpendicularly and travels through it and then through the quartz. In the time it takes the light to travel through the two sheets, how far (in cm) would it have traveled in a vacuum? Number i Units

Suppose you have an unknown clear substance immersed in water, and you wish to identify it by finding its index of refraction. You arrange to have a beam of light enter it at an angle of 45.0° with respect to the normal, and you observe the angle of refraction to be 40.3°. A. What is the index of refraction of the substance?  B. What is its likely identity?

A light ray in the core (n=1.40) of a cylindrical optical fiber is incident on the cladding. A ray is transmitted through the cladding (n= 1.20) and into the air. The emerging ray makes an angle 02 = 6.10° with the outside surface of the cladding. What angle 01 did the ray in the core make with the axis? Air

In vacuum, light is traveling at a 15 degree angle (with respect to the normal) before entering an unknown substance. While in the unknown substance, the light refracts to an angle of 70 degrees (with respect to the normal). Is this possible? O Yes. O No, the angle cannot change more than 45 degrees when going from one substance to another O No, there is no refraction when going from vacuum to another substance, since n1 for vacuum. O No, the index of refraction would have to be less than 1

A A ray of light travels from air to liquid by making an angle of incidence 24°and angle of refraction of 18°. Find R.I. of the liquid. Determine the wavelength in liquid if frequency of light 5.4 × 1015 Hz and C, = 3 × 10 m/s.

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.
