When light goes from one material into another material having a HIGHER index of refraction
 
  A) its speed, wavelength, and frequency all decrease.
  B) its speed and wavelength decrease, but its frequency stays the same.
  C) its speed decreases but its wavelength and frequency both increase.
  D) its speed decreases but its frequency and wavelength stay the same.
  E) its speed increases, its wavelength decreases, and its frequency stays the same.

Question 2

A diffraction grating is to be used to find the wavelength of the light in the emission spectrum of a gas. The grating spacing is not known,
 
  but a light having a known wavelength of 632.8 nm is deflected by 43.2 away from the central maximum in the second order by this grating. Light of the wavelength to be measured is deflected by 48.2 away from the central maximum in the second order. What is the wavelength of this light?

Did you know?

People who have myopia, or nearsightedness, are not able to see objects at a distance but only up close. It occurs when the cornea is either curved too steeply, the eye is too long, or both. This condition is progressive and worsens with time. More than 100 million people in the United States are nearsighted, but only 20% of those are born with the condition. Diet, eye exercise, drug therapy, and corrective lenses can all help manage nearsightedness.
