As you switch from a lower to a higher power objective in a microscope, the brightness of the image typically decreases. This occurs because higher power objectives have smaller apertures, which allow less light to enter. Additionally, the increased magnification can result in a lower light intensity per unit area of the image. Therefore, it may be necessary to adjust the illumination or use a higher intensity light source to maintain a clear view at higher magnifications.

In which objective is the light darker brighter?
In photography, the brightness or darkness of light can change based on the objective or lens used. Typically, a lens with a wider aperture (lower f-number) allows more light to enter, resulting in brighter images. Conversely, a lens with a smaller aperture (higher f-number) restricts light, making images darker. Additionally, the focal length can affect exposure; longer focal lengths may require adjustments to maintain brightness.
What is a stars brightness known as?
A star's brightness is known as its magnitude. Stars with lower magnitude numbers are brighter than stars with a higher magnitude number.
What indicates a stars temperature and brightness?
A star's temperature is indicated by its color, with hotter stars appearing blue and cooler stars appearing red. Brightness is measured using the star's apparent magnitude, with higher magnitudes representing dimmer stars and lower magnitudes representing brighter stars.
Which objective lens would have the greatest field of view?
The objective lens with the lowest magnification typically has the greatest field of view. For example, a 4x objective lens will provide a wider field of view compared to higher magnification lenses like 10x or 40x. This is because lower magnification allows more of the specimen to be visible in the microscope's field.
Which waves have lower frequency radar waves or visible waves?
Radar waves have a lower frequency that light waves.The frequency of a light wave is related to wavelength and speed by the equation c = »½. The color of a light wave is also determined by the frequency. The amplitude and brightness are not related to the frequency.
What happens to length of objective when you change from low to high manification?
Objectives for higher magnification are usually longer than those for lower magnification ...

What is the function of the lower objective on a microscope?
The lower objective on a microscope helps to provide initial magnification of the specimen. It typically has a lower magnification power compared to the higher objectives. This objective is usually used for scanning the specimen and locating areas of interest before moving to higher magnifications.
When moving from a lower objective lens to a higher objective lens why does is the image lost?
Because during movement of lens there is no slide below objective .
What is a stars brightness known as?
A star's brightness is known as its magnitude. Stars with lower magnitude numbers are brighter than stars with a higher magnitude number.
How can you stop sun glare when using a laptop ouside?
look just higher or lower the brightness of your laptop according to condition it happens to me all the time sometimes when i am at a friends house and we sit outside on the porch i just lower or higher the brightness depends how much shade u get
Why is locating an object more difficult if you start with the high-power objective rather than the low power obejctive exspically the brightness whats up with that?
The reason it is more difficult is that the 'field of view' is much smaller, the higher the objective power. In other words, you don't have to be so exactly 'on target' with a lower objective power, as the field of view is larger in proportion to the object being viewed, so the object can be farther off to one side or the other, and still be seen. Once found in the lower power field, center the object in the field and then switch to the higher power- the object should then be in the higher power field of view. This is true for microscopes and telescopes, as well as any instrument that magnifies at different powers of magnification.
How are the numbers related to the length of the objective?
Because the length of the objectives depends on the total magnification. Example: Magnification: 50x (LPO) You can see that the lower the magnification,the length of objective is the smallest. Magnification: 500x (HPO) You can see that the higher the magnification, the length of objective is bigger than the other objectives. If the objective is lower, the number is lesser -Guinean026
How does the temperatures change as you go higher up in space?
Becomes lower and lower.
How do you adjust the monitor brightness in compaq 610 model with xp oprating system service pack 2?
Press and hold the fn key (second from left in bottom row) while pressing either f7 for lower brightness or f8 for higher brightness level.
What is a process improvement objective?
It is (one of) the reason(s) you want to change a work process in an organization. It also tells you what you want/need to achieve by changing the workprocesses.Examples are:- faster throughput- reduced waste- lower cost- higher employee satisfaction- higher customer satisfaction
What determines the brightness of a light bulb?
The brightness of a light bulb is determined by the amount of electrical energy it receives, which affects the intensity of the light produced. A higher wattage bulb will generally be brighter than a lower wattage bulb.
