Radial keratotomy is one of several surgical techniques to correct nearsightedness, reducing or eliminating the need for corrective lenses.
Thermal infrared.
Solar energy is best suited for regions that receive a high amount of sunlight, such as the southwestern United States, due to the optimal conditions for solar panel efficiency. These areas typically have long sunny days and minimal cloud cover, which allows for maximum solar energy production.
Not necessarily. A circular orbit around a central body, such as a planet, would also have a radial velocity of zero at all times. In a circular orbit, the satellite's velocity vector is always perpendicular to the radius vector, resulting in a constant radial velocity of zero.
A polarizing light microscope is best suited to observe birefringent minerals and fibers. This type of microscope is specifically designed to analyze samples that exhibit optical properties like birefringence when light passes through them. The polarizing filters in this microscope help to reveal different colors and textures in the sample, making it ideal for studying birefringent materials.
concave mirror are the best as it collects the sunlight coming from infinity to a single point called focus.it produces intense heat to cook food easily.still using plane mirror on household level for solar cooker is foolishness.

Myopia
Radial Keratotomy or RK is used to treat nearsightedness also known as myopia. This procedure was developed by Svyatoslav Fyodorov a Russian optamologist in 1974.
A radial keratotomy is performed to treat nearsightedness (myopia). It involves making incisions in the cornea to flatten its steep curvature and improve vision.

Correcting nearsightedness
The surgeon uses a delicate diamond-tipped blade, a microscope, and microscopic instruments to make several spoke-like, "radial" incisions in the nonviewing (peripheral) portion of the cornea.
photorefractive Keratectomy
Radial keratotomy (RK) is a surgical procedure to correct nearsightedness by making incisions in the cornea. This procedure does not specifically sharpen any of the five senses. However, it can improve vision by reducing nearsightedness, thereby potentially enhancing the sense of sight. Overall, RK primarily targets vision correction rather than directly sharpening any specific senses.
make several spoke-like "radial" incisions in the non-viewing (peripheral) portion of the cornea. As the incisions heal, the slits alter the curve of the cornea, making it more flat, which may improve the focus of images onto the retina
