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.
A star's brightness is known as its magnitude. Stars with lower magnitude numbers are brighter than stars with a higher magnitude number.
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.
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.
Stars' brightness is measured from Earth using a scale called apparent magnitude. The lower the apparent magnitude value, the brighter the star appears in the sky. This scale is logarithmic, so each higher whole number on the scale corresponds to a decrease in brightness by a factor of about 2.5.
Objectives for higher magnification are usually longer than those for lower magnification ...
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.

Because during movement of lens there is no slide below objective .

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
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.
Becomes lower and lower.
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
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.
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
The frequency of the sound wave must change in order to change the pitch of a sound. A higher frequency results in a higher pitch, while a lower frequency results in a lower pitch.
