Light reflection is when light bounces back after hitting a surface, while light refraction is when light bends or changes direction when it passes through a material

Mensuration is a branch of mathematics that deals with the calculation of the geometric properties of 2D and 3D shapes.. Like 1) Cube 2) Cuboid 3) Sphere 4) Cone

Mensuration is a branch of mathematics that deals with the measurement of the area, volume, length, and other dimensions of 2D and 3D geometric shapes. Here are some formulas for calculating the area of different shapes: Rectangle: \(a\times b\) Square: \(a\times a\) Triangle: \(\frac{1}{2}b\times h\) Parallelogram: \(b\times h\) Circle: \(\pi r^{2}\) Trapezium: \(\frac{1}{2}h(a b)\)
