Answer 1

${\huge {\overbrace {\underbrace {\red{answer:}}}}}$

MAGNIFICATION:-

Magnification is the act or process of magnifying something.Magnification is the degree to which a lens, mirror, or other device can magnify an object, or the degree to which the object is magnified.

The Law Of Reflection:-

The law of reflection states that when a ray of light reflects off a surface, the angle of incidence is equal to the angle of reflection.

THE LAW OF REFRACTION:-

The incident ray, reflected ray and the normal, to the interface of any two given mediums; all lie in the same plane. The ratio of the sine of the angle of incidence and sine of the angle of refraction is constant.

OPTICAL DENSITY:-

Optical density is the process of transmission of light or other electromagnetic radiation by matter. The process of emission and absorption depends on the radiation's wavelength, which includes the interaction between fundamental particles

THE CRITICAL ANGLE:-

The critical angle = the inverse function of the sine (refraction index / incident index). The equation is: θcrit = sin-1(nr/ni)

Answer 2

Answer:

Magnification

magnification is the phenomenon in which harmful chemicals enter in the food chain and its concentration increases at each tropic level.

It is maximum at highest tropic levels and minimum at lowest tropic levels. For example, it is higest in humans and lowest in autrophs like plants.

Law of reflection

The law of reflection states that when a ray of light reflects off a surface, the angle of incidence is equal to the angle of reflection

Optical density

Optical density is the process of transmission of light or other electromagnetic radiation by matter. The process of emission and absorption depends on the radiation's wavelength, which includes the interaction between fundamental particles like electrons, atoms, ions, etc.

Critical angle

The critical angle is defined as the angle of incidence that provides an angle of refraction of 90-degrees. Make particular note that the critical angle is an angle of incidence value. For the water-air boundary, the critical angle is 48.6-degrees.
