Explanation:
In phase-contrast objective and a phase contrast optical systems is equipped with Light microscope .
Phase contrast microscope is used to differentiate unstained structures in a cell that differ in refractive indices and thickness. Thus it is usefull for examining living unstained organisms.
Light that passed through materials of different refractive index and/or thickness will undergo a change in Phase. The difference in phase or wave front irregularities cause variation in brightness of the structures.

Essentially traits of both genes will be shown. Take heterochromia for example, where a person has a green eye and a blue eye, both have some part in developing a trait.
The colors for the stars are red, white, blue-white, white, and blue, and their temperature are 3,910 K, 3,500 K, 25,200 K, 22,400K, 5,780K, 9,600 K.
<h3>What is a star?</h3>
A star is a type of celestial body that can be set apart from others because it shines due to inner radiation. Moreover, stars are classified by:
- Color
- Size
- Location
- Temperature
- Age
Now, let's identify the color and temperature of the stars:
- Aldebaran: This star has a temperature of 3,910 K and its color is red.
- Betelgeuse: This star has a temperature of 3,500 K and its color is red.
- Sirius B: This star has a temperature of 25,200 K and its color is white.
- Spica: This star has a temperature of 22,400K and it is a blue-white star.
- The Sun: This star has a temperature of 5,780K and its color is white.
- Vega: This star has a temperature of 9,600 K and it is a blue star.
