The object is 1m away and the person is 3m away so it would be 3m +1m + the 1m behind the mirror so it would be 5m.

Thanks for your help!

as it passes through each sheet .5 is passed through each polarizer and there is three of them so would you take .5 x .5 x .5 = .125 which would be E. Io/8 ?

Ok so now that I am thinking about, is the image behind the mirror or in front. I am starting to think it is behind?

The image is located in front of the mirror. Isn't the image distance equal to the object distance. Thus it would be 3m

Light known to be polarized in the horizontal direction is incident on a polarizing sheet. It is observed that only 15 percent of the intensity of the incident light is transmitted through the sheet. What angle does the transmission axis of the sheet make with the horizontal? I am not quite...

An unpolarized beam of light is incident on a group of three polarizing sheets that are lined up so that the characteristic direction of each is rotated by 45 degrees clockwise with respect to the preceding sheet. What is the fraction of the incident intensity Io that is transmitted? a. zero...

Do you mean that it is in an angle? I am not quite sure of the answer you are looking for

An object is placed 1m in front of a plane mirror. An observer stands 3m behind the object. For what distance must the observer focus his eyes in order to see the image of the object? My guess is that the observer would have to focus their eyes 3m in order to see the image because when the...

The sugar concentration in a solution can be measured conveniently by using the optical activity of sugar nad other asymmetric molecules. In general, an optically active molecule like sugar will rotate the plane of polarization through an angle that is proportional to the thickness of the sample...

Yeah that is all the question was. How did you figure that out?

An object is placed 1m in front of a plane mirror. An observer stands 3m behind the object. For what distance must the observer focus his eyes in order to see the image of the object?

Does the principle of optical reversibility hold for reflection as well as refraction?

I am trying to understand the laws of reflection better. I know that if a large flat mirror is placed on one wall of a room that the room appears larger than it actually is, but by how much? Is it exactly twice as big? Also, How does the size of the image that is reflected from a plane...

a. The reactance of an inductor is 100 ohms at 2kHz. What is the inductance of this inductor?? b. At what frequency is the reactance of a 3.5-mH inductor equal to 10 ohm? I am not even sure what equations to use for these two questions. I know that for a the inductive reactance equation...
