How does visible light interact with objects to produce the colors we see?​

Physics
1 answer:
Kipish [7]4 years ago
3 0

Answer:

Visible light when all put together is white. When objects appear to be, lets say, red, it would be the only color not absorbed by that object. same goes with all other colors. So black objects absorb all colors (not 100%) and that is why black clothing gets hotter, it simply absorbs all incoming light, as apposed to white that will reflect the colors back, making all of them together appear white. Hope this helps, not the best at explaining things.

An FM radio station broadcasts at 9.23 × 107 Hz. Given that the radio waves travel at 3.00 × 108 m/s, what is the wavelength of
STALIN [3.7K]

Answer:

3.2m

Explanation:

Given parameters:

Frequency of the FM radio = 9.23 x 10⁷Hz

Velocity of the waves = 3  x 10⁸m/s

Unknown:

Wavelength of the wave = ?

Solution:

To solve for the wavelength of the wave, we need the velocity equation;

       Velocity = frequency x wavelength.

Radio waves are all electromagnetic radiations produced by both electrical and magnetic fields perpendicularly oriented to one another.

 Since the unknown is wavelength, we solve for it:

       

    3  x 10⁸  = 9.23 x 10⁷ x wavelength

          wavelength = \frac{ 3 x 10^{8} }{9.23 x  10^{7} }

        wavelength = 3.2m

PART ONE
Arte-miy333 [17]

Explanation:

Pressure = force / area

P = (68 kg × 9.8 m/s²) / (2 × (0.04 m)²)

P = 208,250 Pa

Converting to psi:

P = 208,250 N/m² × (0.225 lbf/N) × (0.0254 m/in)²

P = 30.2 psi

With a total force of 20,000 newtons, an airplane has a mass of 1,200 kg. What is its acceleration?
swat32

Answer:

<h3>The answer is 16.67 m/s²</h3>

Explanation:

The acceleration of an object given it's mass and the force acting on it can be found by using the formula

a =  \frac{f}{m}  \\

f is the force

m is the mass

From the question we have

m =  \frac{20000}{1200}  =  \frac{200}{12}  \\  = 16.66666...

We have the final answer as

<h3>16.67 m/s²</h3>

Hope this helps you
