A red laser from the physics lab is marked as producing 632.8-nm light. When light from this laser falls on two closely spaced slits, an interference pattern formed on a wall several meters away has bright red fringes spaced 6.00 mm apart near the center of the pattern. When the laser is replaced by a small laser pointer, the fringes are 6.18 mm apart. What is the wavelength of light produced by the pointer?
A laser with red light has a frequency of 462 Hz(tera herz=1012 Hz) passes through a double slit. A pattern of interference is observed on a screen that is located 5m from the double slit. The distance to the second order is 80 cm. Determine: a) Wave length of the laser b) Separation of the slits

Question 5 (1 point) Light from a red laser travels at the speed of light (3.00 x108 m/s) and has a wavelength of 650 x10-9 meters. What is its frequency in Hz? 0.0046 4.62 x10-4 4.62 x1014 O2.17 x10-15
block? ght to illuminate structures 20.14 A diagnostic device uses a bright red laser light to illuminatest just under the surface of the skin. Light from the laser passes first through the air. and then the skin, to scatter off the sub- Fi cutaneous structures that are to be im- aged. The scattered light passes back pl through the skin and into an optical de- vice which forms an image of the scat- tered light on a CCD array. The...
