Refractive Index Problem invloving prism (Please Help) Homework Statement What is given is a prism, angle of deviation and apex angle, I also have to find refractive index of the prism. To solve the problem I must prove that: [SIZE="2"]Nprism = sin((A+d)/2)/ sin(A/2) The diagram...

[SOLVED] Light Refracted Through A Prism Homework Statement Two parallel rays enter the longest side of a prism of refractive index 1.52. The prism is isosceles in shape and has angles of 23, 23 and 134 degrees. Assuming that the rays enter the prism on either side of the perpenical divider...

i was just wondering why blue light is bent more than red light when light is passed through a prism. Could someone explain this? Also, when light goes through glass with an index of refraction>1, why is the angle of refraction less than the angle of incidence?

Homework Statement There is a rectangular prism of uniform mass distribution with lengths of a, b, and c (b>a>c). Calculate it's rotational inertia about an axis through one corner and perpendicular to the large faces.Homework Equations I = \int r^2 dm r^2 = x^2 + y^2 + z^2 \rho =...

Which makes a better prism?? Homework Statement Hey guys, I'm helping my girlfriend once again, in physics 101! I'm not used to these "theory" questions...haha Anyways, the question asks:Which would make a better prism, a diamond or glass? I guess, I chose glass...because a diamond...

Hi, I have a question about the dispersion of white light in prism. Why different color of light have different speed in prism ? What properties of light affect its speed ?

Homework Statement Find the moment of inertia of triangular prism (equilateral triangles with side 2a, parallel to xy-plane), mass M. It's centered at the origin with long side parallel to z-axis. Find moment of inertia about the z-axis, and without doing integrals explain two products of...

A trinagular prism is 10 m long and has an equilaterlal trinagle for its base. WAter is added at a rate of 2m^3/min. Determine the rate of change of the water level when the water is \sqrt{3} m deep. ok so the volume of a prism is V = \frac{1}{2} lwh ... (1) l is the length w is the...

I am looking for a mathematical derivation for the idea that symmetry of the light beam path through a prism gives rise to a minimum deviation. Thanks.

can i use a prism to diffract(separate?) ultralight or microwaves, if so, how far into the spectrum will it go? for example, when i look at a rainbow, and the rainbow ends after the violet and before the red, does it really end? or am i just unable to see the missing wavelengths?

A shaft of light passes through a prism with refracting angle \theta and refractive index n . Let \alpha be the deviation angle of the shaft. Demonstrate that if the shaft of light passes through the prism symetrically the angle \alpha is the least?

Light of wavelength 700 nm is incident on the face of a fused quartz prism at an angle of 80.0° (with respect to the normal to the surface). The apex angle of the prism is 60.0°. Use the value of n from Figure 35.20, to calculate the following angles. (a) the angle of refraction at the first...

When bulb light passes through a prism why doesn't it give different colors? From what I understood about light bulbs, it should give red, orange and yellow as descrete lines. Why doesn't this happens and it goes out of the prism almost as it enters? Thanks

What is so special about a glass prism that a beam of light disperses after passing through it but not an ordinary cuboidal glass prism?

I think I posted my thread in the wrong section. Hopefully someone can help me get started with this problem please. Thanks a lot. The figure is a right angle triangle with 30-60-90 degree angles (right angle). The glass prism shown has an index of re- fraction that depends on the...

Hi, could someone please help me get started on this problem. The figure is a right angle triangle with 30-60-90 degree angles (right angle). Can you help, please. Thank you so much. The glass prism shown has an index of re- fraction that depends on the wavelength of the light that enters...

If you have two prisms on top of each other, one smaller than the other, and the one on top glids down to the ground the lower prisms moves to the left. The problem is to find how far the lower prism moves. How do you set up the Lagrangian and the constraints for this problem? Any ideas?

A prism shown i has a refractive index of n, and the angles A are theta. Two light rays m and n are parallel as they enter the prism. What is the angle between them after they emerge?(In radians)

Hello, I have a question concerning the angle of deviation of the rays that exit out of the wollaston prism. (A wollaston prism is basically composed of two different crystal orientated blocks cemented together, each having a different index of refraction depending on the optical axis) My...

There is a rectangular prism (L x W x H) = (72 x 36 x 8). The center of mass is 31 inches from one end lengthwise, and centered heightwise and widthwise. I drew an image: http://www.xdemi.com/hovcalc/delirium.bmp Basically, we need the moment of inertia of this object. Two forces are...

Light of wavelength 700 nm is incident on the face of a fused quartz prism at an angle of 61.0 degrees (with respect to the normal to the surface). The apex angle of the prism is 60.0 degrees. Using the n value of 1.46, find: (a) the angle of refraction at the surface > I did this and...

Hi, i need to deduce the Fresnel Double Prism equation, which states: d = 2a(n-1)alpha, according to the linked image. http://www.du.edu/~jcalvert/waves/biprism.gif The distance between the constructed virtual objects S' and S'' is here called d. The distance from the light source to...

The Question: A 45-45-90 prism is immersed in water. What is the minimum index or fefraction the prism must have if it is to reflect totaly a ray incident normally on one of its faces. Now, we have found this question a bit hard to understand. We assume that light is hitting one of the...
