In three-dimensional geometry the equations of the x-axis are given by y = 0 and z = 0 since all points on the x-axis have y and z coordinates equal to zero. In parametric form the x-axis is represented as ...
In Class 12 Maths Three Dimensional Geometry the reflection of a point across a plane is found by using the perpendicular distance formula. The image of a point is equidistant from the plane but on the opposite side. This concept ...
Cosines represent the ratio of the adjacent side to the hypotenuse in a right triangle. They help define wave oscillations, circular motion, and Fourier analysis. The cosine function is periodic, with a range from -1 to 1, and plays a ...
Wavelength is the distance between two consecutive crests or troughs of a wave. It is commonly used to describe electromagnetic waves like light, radio, and sound. Wavelength is inversely proportional to frequency, meaning longer wavelengths have lower frequencies and shorter ...
Temperature is a measure of the average kinetic energy of particles in a substance. It determines the direction of heat flow between objects with heat moving from higher to lower temperature. Temperature is measured in units such as Celsius, Kelvin ...
Energies of radiations refer to the energy carried by electromagnetic waves across different wavelengths. These include visible light, ultraviolet, infrared, X-rays, and gamma rays. The energy of radiation is directly proportional to its frequency and inversely proportional to its wavelength, ...
A black body in physics is an idealized object that absorbs all incident radiation regardless of wavelength. It also emits radiation at maximum efficiency for any given temperature. The concept of a black body helps in understanding heat transfer and ...
Mud houses are traditional dwellings made using natural materials like clay and mud. These houses are eco-friendly cost-effective and provide good insulation against heat and cold. Mud houses are commonly found in rural areas and offer a sustainable living option ...
Temperature is a measure of the average kinetic energy of particles in a substance. It determines the direction of heat flow between objects, moving from higher to lower temperature. Measured in units like Celsius, Kelvin or Fahrenheit, temperature plays a ...
