Nearly all light that strikes a transparent object will be absorbed by the object.

Answer:

Black colored

Explanation:

Every object in this world reflect some part of the light and absorb some part of it. Also, the visible light is made up of seven colors. So when light falls on an object all the seven colors are falling on it but the color of the object will be a mixture of all the colors being reflected by object. If all the colors are reflected we will white color.

The object which is in black color will absorb all the light and thus it looks black in color. No part of light is reflected back.

laila [671]

Answer:

$d=2.77\cdot 10^6\ Km$

Explanation:

<u>Speed</u>

The speed is calculated as the ratio of the distance d by the time t:

$\displaystyle v=\frac{d}{t}$

If we need to calculate the distance, the equation is solved for d:

d=v*t

The speed of light is

$v=3\cdot 10^5\ Km/s$

It takes t=9.221 seconds for light reflected from the moon Vega to reach planet Xartan.

We can calculate the average distance the light traveled:

$d=3\cdot 10^5\ Km/s*9.221$

$d=2,766,300\ Km$

Or, in scientific notation:

$\mathbf{d=2.77\cdot 10^6\ Km}$

goldenfox [79]

Answer:

Water in an artificial lake held behind a dam

Explanation:

Potential energy is energy that can be converted to kinetic energy, for example, an object at a certain height has potential energy because we can drop the object to have kinetic energy.

Therefore, the best example of potential energy is water in an artificial lake held behind a dam because without the dam, the water will start to move and it becomes the energy into kinetic energy.

Please match the words to the definitions!!

andrey2020 [161]

Explanation:

1. The Centauri star system consists of 3 stars and is about 4.37 light-years away from Earth. (A light-year is the distance that light travels in a year.)

2. We see the visible spectrum which consists of colors red, orange, yellow, green, blue, indigo, and violet. (The visible spectrum is the range of light that our eyes can detect.)

3. Because air has a lower index of refraction than water, the light beams making up the image of the fish I see bends as it leaves the water and enters the air. (Index of refraction determines how light bends when moving from one medium into another.)

4. When I look at my reflection in the mirror, the light reflects off the mirror at an equal but opposite angle as it hits the mirror.

5. When looking into a concave mirror the center is further away from you than the outside edges. (Concave mirrors cave in.)

6. Forklift drivers are careful to look in the convex mirrors placed at blind intersections in the warehouse.

7. is transparent and the light goes through without distortion.

8. The electromagnetic spectrum refers to any or all of the possible wavelengths of "light", both the visible light and invisible light.

9. The transmission of light through a medium means it goes through it.

10. The absorption of light by a medium means it is absorbed by it.
