Answer :
The angle of refraction will be 26.4°
Organic substances include ethanol. With the chemical formula C2H6O, it is a straightforward alcohol. Its chemical formula can also be expressed as C2H5OH or CH3CH2OH. Ethanol is a volatile, flammable, colorless liquid with a pronounced wine-like aroma and unpleasant taste.
The angle of incidence is the angle formed by an incident ray and the normal, or line perpendicular to the incident surface, at its point of incidence. Any type of wave, including optical, acoustic, microwave, X-ray, and others, can create a ray.
Refraction is the path of a light wave being bent as it crosses the divide between two media. Refraction results from a wave's change in speed when it encounters a change in medium.
The angle of refraction, which depends on the material's refraction index, is the degree by which this light bends away from or toward the normal line. Each type of material has its own constant known as the refraction index. The amount that an incident light beam is refracted as it passes through directly affects it. It is frequently represented as n and may be calculated by dividing the velocity of light moving through the medium (v) by the speed of light in a vacuum (c):
n = c / v
