3. What are some questions that philosophers ask about knowledge?

Mariulka [41]

Hello there,

<span>What are some questions that philosophers ask about knowledge?

I hope I would be understanding your question right. But I believe that on question they could ask is " What part in the human brain could store up all this knowledge that any human can store".

I truly hope this helps.

If the light strikes the first mirror at an angle θ1, what is the reflected angle θ2? express your answer in terms of θ1.

Alexus [3.1K]

Answer:

θ₂ = 90° - θ₁

Explanation:

When the light falls on a mirror it bounces back. This is know as reflection. The incident angle is equal to the angle of reflection.

Here, the light strikes the mirror at an angle = θ₁

To find the angle of reflection we first need to understand angle of incidence. The angle of incidence is the angle made between the incident ray and normal. Normal is an imaginary line drawn perpendicular line on the boundary of the mirror.

Since the light strikes the mirror at angle of θ₁, which is the angle between light ray and the mirror.

Angle of incidence = 90° - θ₁.

Thus, angle of reflection, θ₂ = 90° - θ₁
