Constants SOLUTION Light rays that enter your eye are affected by the fluid that fills the eyeball, called the vitreous humor (Figure 1). When red light from a l = 633 nm helium-neon laser enters your eye, its wavelength drops to 474 nm. Use this information to calculate the index of refraction of the vitreous humor and the speed and frequency of light passing through it. SET UP AND SOLVE We don't need to sketch this problem because we're interested...

Practice | MCAT P QUESTION If the air wedge is filled with water, how are the wavelength and the distance between dark bands affected? (Select all that apply.) The wavelength decreases. O The wavelength increases. The interference bands get farther apart. O The interference bands get closer together Recall how the wavelength is affected by the index of refraction of the medium. See equation below and the surrounding material for help. Does a shorter wavelength make...

This scenario is for questions 1-2 A simple harmonic oscillator at the position x-generates a wave on a string. The oscillator moves up and down at a frequency of 40.0 Hz and with an amplitude of 3.00 cm. At time t=0, the oscillator is passing through the origin and moving down. The string has a linear mass density of 50,0 g/m and Is stretched with a tension of 5.00 N. a) Find the...
