What does GC mean in PHYSICS
GC stands for Geometrical Correction. This term is commonly used in the field of science and engineering, particularly when dealing with lighting or illumination technologies. Geometrical correction is a kind of adjustment aimed at creating a better and more uniform light distribution over an area when using various lighting devices.

Essential Questions and Answers on Geometrical Correction in "SCIENCE»PHYSICS"
How do I know if my image needs Geometrical Correction?
Geometrical correction is needed when an image becomes distorted due to incorrect positioning of the camera during the shooting process. Signs of distortion include curved lines, skewing of objects in the frame, and uneven dimensions.
What type of editing tool can I use for Geometrical Correction?
There are many software options available for geometrical correction, including Graphic Design softwares such as Adobe Photoshop and CorelDRAW. Additionally, some photo editors such as Adobe Lightroom have built-in tools specifically for this purpose.
Can I apply Geometrical Correction to photos taken from a phone?
Yes, it is possible to apply geometrical correction to photos taken from a smartphone using a suitable photo editor or design software application. You may need to transfer the images to your computer first.
What can be corrected with Geometrical Correction?
Most common distortions that can be addressed with geometrical corrections are perspective distortion, rotation distortion and keystone distortion/distortion caused by lens curvature.
Is Geometrical Correction necessary for all photos?
No, it is not necessary for all photos but may be needed for particular types of shots or those that contain elements that appear skewed or curved due to camera position or lens curvature.
Can I undo Geometrical Corrections once completed?
Yes, most graphic design softwares allow you to undo any changes made when performing geometrical corrections on an image. It is recommended to save a copy of the original image before making changes in case you want to revert back later on.
Are there limitations on how much Geometric Correction I can apply on an image?
Generally speaking, some degree of geometric correction can be applied without reducing the overall quality of an image too much although results may vary depending on the size and resolution of the original photo. It is important not to overdo the adjustments as this may degrade picture quality considerably.
Will applying Geometric Corrections affect all parts of my photo equally?
No, applying these corrections will usually not affect all parts of a photo equally but rather adjust certain elements more than others according to their relative positions within the frame and where adjustments have been made.
Is there any way I can preview what my photo will look like after performing Geometric Corrections?
Yes, many software applications offer a preview window which allows you to see what your edits will look like before committing them permanently onto your image file. This is often indicated by a small 'preview' button located next to each editable option in your software window.
Final Words:
In conclusion, GC stands for Geometrical Correction which is an important element in optimizing illumination performance for various types of lighting systems such as LEDs, florescent lamps and laser diodes. Through applying appropriate techniques such as homogenization or masking masks, geometrical correction can help create better uniformity and efficiency while minimizing glare and shadows from bright spots in order to achieve optimal illumination for a specific area or space.
