The color of wavelengths that shown at color 1 is <u>(A). Red light</u>.
<h3>Introduction</h3>
Hi ! Here, I will help you to explain about the refraction of light. When a visible light is bent by water droplets or a prism lens, it will undergo refraction. Refraction will cause light that appears chromatic to be divided into <u>seven spectra, namely: red, orange, yellow, green, blue, indigo, and purple</u>. The order has been ordered from the wavelength, and the red color has the longest wavelength so that it is located at the top and looks the most curved.
<h3>Explanation</h3>
Based on the image, the part of the light that will come out of "number one" is the red light. In accordance with the initial agreement, that red has the longest wavelength. With this feature, red is very easy to bend to "overshadow" the color spectrum with shorter wavelengths. As a comparison :
- The light that will come out from "number two" is a yellow light. Yellow light has a shorter wavelength than red.
- The light that will come out from "number three" is a green light. Green light has a shorter wavelength than yellow.
- The light that will come out from "number four" is a blue light. Blue light has a shorter wavelength than green.
<h3>Conclusion</h3>
The color of wavelengths that shown at color 1 is (A). Red light.

Answer:
The object displacement is 0 meters.
Explanation:
Because the expression for the object position as function of time is:
At t= 3.0=t2 seconds the x-position of the object is:
and at t=1.0=t1 seconds the x-position of the objects is:
The total displacement () of the object between t2 and t1 is the difference between x(3.0s) and x(1.0s):
The displacement of the object is zero!!!
Answer:
Explanation:
When 2 gms of steam condenses to water at 100 degree latent heat of vaporization is releases which is calculated as follows
Heat released = mass x latent heat of vaporization
= 2 x 2260 = 4520 J
When 2 gms of water at 100 degree is cooled to ice water at zero degree heat is releases which is calculated as follows
Heat released = mass x specific heat x( 100-0)
= 2 x 4.2 x 100 = 840 J
When 2 gms of water at zero degree condenses to ice at zero degree latent heat of fusion is releases which is calculated as follows
Heat released = mass x latent heat of fusion
= 2 x 334 = 668 J
When 2 grams of steam at 100 degrees Celsius turns to ice at 0 degrees Celsius heat released will be sum of all the heat released as mentioned above ie
4520 + 840 +668 = 6028 J
