3. True or false?
Forensic psychiatrists and psychologists never create behavioral profiles in order to help law enforcement officials identify and catch suspects.

explanation:

v=uf/(u-f)

= 5.-10/(5+10) convex lens has negative focal length

a.) travels faster in solids because the particles are closer together.

air is a gas water is a liquid

speed of light in vacuum is 300,000 km/s

speed of light in other mediums is given by the expression v = c/n, where c is the speed of light in vacuum and n is the refractive index of medium.

for the first medium v = 200,000 km/s

  so, refractive index of medium = 300000/200000 = 1.5

    1.5 refractive index is usually for glass. so first medium is glass.

for the second medium v = 250,00 km/s

so, refractive index of medium = 300000/250000 = 1.2

    1.2 refractive index is usually for water. so second medium is water.

for the third medium v = 0 km/s

so, refractive index of medium = 300000/0 = ∞

    ∞ refractive index is usually for opaque mediums. so third medium is opaque medium.
