Explanation Expression for the central diffraction fringe, sin θ = λ d θ is the angle of line from the center of slit array to the first bright region on screen λ is the wavelength of the laser light beam d is the width of the laser beam The intensity of center diffraction fringe increases for the disc which has smaller width. But there is a limit for the magnitude of its width that it cannot be less than the wavelength of the laser beam because in this case sin θ becomes greater than one which cannot be possible

Compton effect

The incoming photons' energy must be in the range of an X-ray frequency to generate the Compton effect. The electron does not lose enough energy that reduces the wavelength of scattered photons towards the visible spectrum. As a result, with visible ligh…

Recoil Velocity

The amount of backward thrust or force experienced by a person when he/she shoots a gun in the forward direction is called recoil velocity. This phenomenon always follows the law of conservation of linear momentum.

Question

To determine

The explanation for limitation on the amount of information that can be stored on the disc is the width of the laser beam. And the explanation for using a shorter-wavelength laser allows more information to be stored on a disc of the same size.

You would like to observe an E. coli bacterium that is 1.95 µm long. Because diffraction blurs an image, you would like to minimize the effects of diffraction by using a wavelength no larger than the object you are observing. For this problem, assume the wavelength is equal to the length of the bacterium. What is the energy of a photon with this wavelength? energy of photon: What is the energy of an electron with a de Broglie wavelength of this size? energy of electron: In terms of energy, which particles, photons or electrons, are the least likely to damage your sensitive biological sample? photons they are the same electrons J J

When John broke his arm, the doctor took an x-ray of John’s arm. John had never seen an x-ray before. He asked the doctor how the x-ray was able to show his bones but not his skin and other tissue. Which explanation would the doctor best provide to John? A X-rays have lower energy than visible light and therefore produce a black background behind the bone image. B X-rays have lower frequency than infrared light and therefore penetrates through the bone. C X-rays have higher frequency than gamma rays and therefore pass through skin and bone. D X-rays have higher frequency than visible light and therefore can pass through skin and tissue but not through the bone.

8: Two flat mirrors are connected to each other such that they make an angle of ψ. A laser enters the system and first reflects off the bottom mirror, then the top mirror. When the beam exits it makes an angle of θ = 126 degrees with respect to the initial beam (see figure). θ = 126 degrees (a) Write an expression for the angle, ψ, between the mirrors. (b) Calculate this angle, ψ, in degrees.

The explanation for limitation on the amount of information that can be stored on the disc is the width of the laser beam. And the explanation for using a shorter-wavelength laser allows more information to be stored on a disc of the same size.

Solution Summary: The author explains that the width of the laser beam limits the amount of information that can be stored on a disc. A shorter-wavelength laser can read the large number of pits.
