How do you find the angle of a reflected ray? The law of reflection states that the angle of reflection equals the angle of incidence—θr = θi. The angles are measured relative to the perpendicular to the surface at the point where the ray strikes the surface. What does it mean to reflect over Y […]

When a stone is thrown vertically upwards its velocity is continuously decreased Why? Kinetic energy(K.E) is given by 1/2 mv^2 where, ‘m’ and ‘v’ are the mass and velocity of the body and Potential energy (P.E) = m×g×h where g and h are acceleration due to gravity and height attained by the body respectively. As […]

Is blue light damaging to skin? Research shows blue light from electronic devices can lead to changes in your skin cells, including cell shrinkage and death. These speed up the aging process. Even exposures as short as 60 minutes can trigger these changes. Too much blue light could also lead to pigmentation. What is blue […]
