According to Rutherford and Soddy made experimental study of the radioactive decay of various radioactive materials and gave the following the laws: Radioactive decay is a random and spontaneous process. It is not influenced by external conditions such as temperature, Read more about Law of Radioactive Disintegration[…] # Complementary Angles

Complementary Angles Theorem: , Proof: Let . . .(1) Where , , , , , Now sin⁻¹x = θ x = sin θ x = cos (π/2 – θ) cos⁻¹x = π/2 – θ cos⁻¹x + θ = π/2. . . (2) from equation 1 and 2 sin⁻¹x = θ cos⁻¹x + θ = π/2 Read more about Complementary Angles[…] # Relation f⁻¹(x) with f⁻¹(-x) – Theorems

Relation f⁻¹(x) with f⁻¹(-x) – Theorems Theorem: . Proof: , Let sin⁻¹(-x) = θ . . . (1) -x = sinθ x = -sinθ x = sin(-θ) we know that x ϵ [-1, 1] and  , -θ =sin⁻¹(x) . . . (2) From equation (1) and (2) sin⁻¹(-x) = θ -θ =sin⁻¹(x) ⇒ θ = Read more about Relation f⁻¹(x) with f⁻¹(-x) – Theorems[…] # Interference of Light

Interference of Light When two waves of exactly same frequency travels in a medium, in the same direction simultaneously then due to their superposition, at some points intensity of light is maximum while at some other point’s intensity is minimum. This phenomenon is called Interference of light. It is of following two types (1) Constructive Read more about Interference of Light[…] # National Law University – All India Law Entrance Test (AILET) 2020 Exam Date Released

Characteristics of Wave Motion Waves can occur whenever a system is disturbed from equilibrium and when the disturbance can travel or propagate from one region of the system to another. Wave can carry energy and momentum. The energy in light waves from the sun warms the surface of our planet; the energy in seismic waves Read more about Characteristics of Wave Motion[…] # Relation f⁻¹(x) with f⁻¹(1/x) – 2

Relation f⁻¹(x) with f⁻¹(1/x) – 2 Theorem: cos⁻¹(1/x) = sec⁻¹(x), for all Proof: cos⁻¹(1/x) = sec⁻¹(x) Let sec⁻¹(x) = θ Where θ ϵ [0, π] –{0} and x = secθ 1/x = 1/ secθ 1/x = cosθ θ = cos⁻¹(1/x) sec⁻¹(x) = θ sec⁻¹(x) = cos⁻¹(1/x) cos⁻¹(1/x) = sec⁻¹(x), for all Hence proved Theorem: Proof: Read more about Relation f⁻¹(x) with f⁻¹(1/x) – 2[…] # Resistivity, Conductivity and Conductance

Resistivity, Conductivity and Conductance 1) Resistivity: Resistivity is a measure of the resistance of a given size of a specific material to electrical conduction. From, , if ,  then  i.e. resistivity is numerically equal to the resistance of a substance having unit area of cross section and unit length. i) Unit and dimension: Its SI Read more about Resistivity, Conductivity and Conductance[…]
