Which statement describes how rays behave when they travel through media during reflection and refraction? During refraction, rays stay in the original medium, and during reflection, rays pass into a new medium.
During reflection, rays stay in the original medium, and during refraction, rays pass into a new medium.
During reflection and refraction, rays stay in the original medium.
During reflection and refraction, rays pass into a new medium.

5 w for 1hr = 5x60x60 joules=300x60=3000x6=18,000j as total energy conversion. efficiency of bulb needed for radiant to thermal within 18000

adding a(n) to an electric circuit would increase the magnetic field around a wire;

b. solenoid

a solenoid is a type of electromagnet whose purpose is to generate a controlled magnetic field.

if the purpose of the solenoid is instead to impede changes in the electric current, a solenoid can be more specifically classified as an inductor rather than an electromagnet.
