I think the correct answer from the choices listed above is option D. The types of heat transfer that allows heat to flow from hot objects to colder object are <span>convection and conduction, but not radiation. Convection and conduction heat transfer happens only when a medium is present while radiation do not need a radiation to occur.</span>
Answer:
compared to the incident angle, the refracted angle is 45.56⁰
Explanation:
From Snell's law;
n₁sin(I) = n₂sin(r)
Where;
n₁ is the refractive index of light in medium 1 = 1.2
n₂ is the refractive index of light in medium 2 = 1.4
I is the incident angle
r is the refractive angle
I = 56.439⁰
Applying snell's law
Therefore, compared to the incident angle, the refracted angle is 45.56⁰
Answer:
C
Explanation:
Ray of light when hits any specimen or object. The light is partially reflected, partially reflected and partially absorbed. It is never completed reflected, refracted or absorbed. Hence, the correct answer would be c.
Meters it the SI unit for measuring length.
