Introduction to SAT II Physics

You can test all this yourself with the right kind of spoon. As you hold it at a distance from your face, you see your reflectio ...

Values of d, , and f are positive if they are in front of the mirror and negative if they are behind the mirror. An object can’t ...

Because is a positive number, we know that the image will be real. Of course, we could also have inferred this from the fact tha ...

In this diagram, the boy is standing far enough from the lens that d > f. As we can see, the image is real and on the opposit ...

As the diagram shows us, and as the two equations for lenses and mirrors will confirm, the image is virtual, appears on the same ...

SAT II Physics questions on optical instruments are generally of two kinds. Either there will be a quantitative question that wi ...

At any point P on the back screen, there is light from two different sources: the two slits. The line joining P to the point exa ...

Because the far screen alternates between patches of constructive and destructive interference, the light shining through the tw ...

Note that the pattern is brightest in the middle, where = 0. This point is called the central maximum. If you encounter a questi ...

Light is a transverse wave, meaning that it oscillates in a direction perpendicular to the direction in which it is traveling. H ...

One of the more common ways of testing wave optics is by testing your familiarity with different terms. We have encountered a nu ...

3.. When the orange light passes from air (n = 1) into glass (n = 1.5), what is its new wavelength? (A) m (B) m (C) m (D) m (E) ...

6.. What is the minimum incident angle for which the light will undergo total internal reflection in the plastic? (A) sin–1 (B) ...

9.. Sound waves do not exhibit polarization because, unlike light waves, they are not (A)Longitudinal (B)Coherent (C)Dispersive ...

formula v = c/n, where c is the speed of light in a vacuum, and n is the index of refraction for the given substance. Since , we ...

E Only concave mirrors and convex lenses can produce images that appear upside down. However, concave mirrors produce these im ...

mistaken. The “modern” physics of the past century focuses on phenomena so far beyond the scope of ordinary experience that Newt ...

For people who believed that light must travel through an ether, the result of the Michelson-Morley experiment was like taking a ...

Einstein’s first postulate tells us that neither the passenger on the train nor the person on the platform is wrong. It’s just a ...
