What happens when visible light strikes a surface?

1 answer:

6 0

Absorption:

If the wavelength of the light happens to match the distance between two electron levels in the material, it can be absorbed. Light disappears and its energy becomes part of the heat energy of the material. 

Metals have so many free electrons that all wavelengths are absorbed -- they are opaque to xrays, visible light, radio waves, everything. 
Pigments have specific electron gaps that absorb only the light of a specific wavelength, which we see as color 
Transparent materials do not happen to have any gaps between electron levels that match any of the wavelengths of visible light.

If Phoenix, Arizona, experiences a cool, wet day in June, does that mean the regions climate is changing?

It doesn't mean that the climate is changing, it is probably just the morning dew.

Given that:

Energy of bulb (Work ) = 30 J,

Time (t) = 3 sec

The power consumption = ?

We know that, Power can be defined as rate of doing work

Power (P) = Work(Energy supplied) ÷ time

= 30 ÷ 3

= 10 Watts

The power consumption is 10 W.

I'm not really sure how to go about creating the equation, can anyone help me?

AlexFokin [52]

The displacement vector (SI units) is
$\vec{r} =At\hat{i}+A[t^{3}-6t^{2}]\hat{j}$

The speed is a scalar quantity. Its magnitude is
$v= \sqrt{A^{2}t^{2}+A^{2}(t^{3}-6t^{2})^{2}} \\ v=A \sqrt{t^{2}+t^{6}-12t^{5}+36t^{4}} \\ v=At \sqrt{t^{4}-12t^{3}+36t^{2}+1}$

Answer: At√(t⁴ - 12t³ + 36t² + 1)
