A scientist wants to design a lens that can correct both myopia and hyperopia. Explain the different lens types required and how they adjust focal lengths.
💡 Hint: Consider how each lens type affects light differently.
Calculate the angle of refraction when light passes from air (n=1.00) into glass (n=1.5) at an incidence angle of 30 degrees. Use Snell's Law.
💡 Hint: Remember to use Snell's Law with refractive indices and angles.
