The iris diaphragm in a microscope regulates the amount of light that reaches the specimen being observed. By adjusting the size of the aperture, it helps control the contrast and resolution of the image, allowing for clearer visualization of details. This feature is particularly important when examining specimens at different magnifications or when using varying illumination techniques. Overall, the iris diaphragm enhances the quality of the microscopy experience.

Porque quanto mais profundo, mais dificuldade tem a luz de atravessar a água do mar. E nem precisa ser no fundo do oceano. Depois de uma certa profundidade a luz já começa a diminuir. Os minerais dissolvidos na água também constituem uma barreira para a luz.
The angular diameter of the full moon is about 0.5 degrees. To calculate the distance at which a dime would have the same angular diameter, you can use the formula: tan(angular size) = (diameter of object) / (distance). Plug in the values and solve for distance to find that you would need to hold the dime approximately 68 meters away from your eye.
Provavelmente está a referir-se ao planeta Vénus, que é frequentemente visível perto da lua e é um dos objetos mais brilhantes no céu noturno. Vénus é o segundo planeta mais próximo do Sol e é conhecido por ser tão brilhante que pode ser visto mesmo durante o dia.
The name Jupiter means "Day Father." It is an old Indo-European word ( dyaus-pita in Sanskrit). How the word Zeus derives exactly is unclear, but its oblique cases, the genitive Dios, dative Dii and accusative Dia, seem to indicate derivation of "Zeus" from the Indo-European word for "day," making it and Jupiter different versions of the same name. Because Romans had different thoughts than the Greeks . they believed in different gods so they changed the names and worship them.
