A red laser pointer has a wavelength of 633 nm. Calculate the following: (3 pts) a. Energy of a photon from this laser pointer in J b. Energy in kl/mol photons c Wavenumber in cm!
Two narrow slits are illuminated by a laser with a wavelength of 514 nm. The interference pattern on a screen located x = 4.60 m away shows that the third-order bright fringe is located y = 9.00 cm away from the central bright fringe. Calculate the distance between the two slits. 7.88×10-3 cm You are correct. Previous Tries The screen is now moved 1.1 m further away. What is the new distance between the central and the third-order bright fringe?...
2. A red laser pointer has a wavelength of 633 nm. Calculate the following: (3 pts) a. Energy of a photon from this laser pointer in b. Energy in kJ/mol photons c. Wavenumber in cm1
A thin beam of laser light of wavelength 514 nm passes through a diffraction grating having 3952 lines/cm. The resulting pattern is viewed on a distant curved screen that can show all bright fringes up to and including ?90.0? from the central spot. If the experiment were performed with all of the apparatus under water (which has an index of refraction of 1.33), what would be the TOTAL number of bright spots that would show up on the screen?
4. Light from a laser has a wavelength of 630 nm in a vacuum. Calculate the wavelength in water. Given the index of refraction is 1.33.
