Light Refraction

Diffraction- Rayleigh criterion

Late one night on a highway, a car speeds by you and fades into the distance. Under these conditions the pupils of your eyes (average refractive index = 1.36) have diameters of about 7.0 mm. The taillights of this car are separated by a distance of 1.4 m and emit red light (wavelength = 660 nm in vacuum). How far away from you i

Refraction problem

Light is reflected from a glass coffee table. When the angle of incidence is 56.0°, the reflected light is completely polarized parallel to the surface of the glass. What is the index of refraction of the glass?

Waves and Refraction

1. The speed all electromagnetic waves in empty space is 3.00 x 10^8 m/s. Calculate the wavelength of electromagnetic waves emitted at the following frequencies: a. radio waves at 88.0 MHz b. visible light at 6.0 x 10^8 MHz 2. A tuning fork produces a sound with a frequency of 256 Hz and a wavelength in air of

Refraction

1. For an incoming ray of light with the vacuum wavelength of 589 nm, fill in the unknown values in the following table. From (medium) To(medium) 0i 0r ---------------------------------------------------- a. Flint glass Crown glass 25.0 ? b. Air ? 14.5 9.80 c.

Light through a filter. Find the thickness of the transparent dielectric.

Astronomers observe the chromosphere of the Sun with a filter that passes the red hydrogen spectral line of wavelength 656.3 nm. The filter consists of a transparent dielectric of thickness d held between two partially aluminized glass plates. The filter is held at a constant temperature. a) Find the minimum value of d that p
