Explanation
Amplitude is the maximum displacement of a wave from its equilibrium position. It is the distance from the rest position to the top of a crest or the bottom of a trough.

Explanation
The wavelength of a transverse wave is the distance between two adjacent crests or troughs. It is a fundamental property of waves and is typically denoted by the symbol λ (lambda).

Explanation
Transverse waves are waves where the particles of the medium oscillate perpendicular to the direction of wave propagation, creating crests and troughs. Examples include light waves, radio waves, and water waves.

Explanation
When a sound wave travels from one place to another , it transports energy from the source of the sound to the surrounding environment. Sound waves are a form of mechanical energy that is transferred through the vibration of particles in a medium, such as air or water.

Explanation
If an object absorbs all seven colors of light (i.e., all the wavelengths of visible light), it appears black . This is because no light is being reflected , and our eyes perceive the absence of light as black. When an object reflects all the  component colors of light, it appears  white .

Explanation
The color of an opaque or non-luminous object is the color of light it reflects . When light hits the object , some wavelengths are absorbed, and the remaining wavelengths are reflected , which is what we perceive as the object's color.

Explanation
A rainbow is a beautiful natural phenomenon that demonstrates the spectrum of white light. When sunlight passes through water droplets in the air, it is refracted and separated into its individual colors, creating the colorful arc of a rainbow. This is a perfect example of the spectrum of white light.

Explanation
A spectrum is a band of seven colors that appear when white light is passed through a prism or a similar device , separating the different wavelengths of light. The seven colors of the spectrum, in order, are : Red Orange Yellow Green Blue Indigo Violet

Explanation
When light passes through a prism , refraction occurs, leading to the formation of a spectrum. Refraction is the bending of light as it passes through a medium with a different optical density. It causes the different wavelengths of light to separate and form a spectrum.

Explanation
Dispersion of light refers to the splitting of white light into its component colors, which are also known as the visible spectrum. This occurs when light passes through a medium with a refractive index that varies with wavelength, such as a prism.

Explanation
Convection is the primary mode of heat transfer in liquids and gases , where heat is transferred through the motion of fluids. This motion creates circulation currents that carry heat energy from one location to another.

Explanation
Convection is the mode of heat transfer that occurs when a fluid (such as a gas or liquid) moves and carries heat energy from one location to another. This transfer of heat occurs due to the bulk motion of the fluid.

Explanation
During nighttime, the air above the land loses heat and cools down , causing its density to increase. This is because cool air contracts and becomes denser than warm air.

Explanation
The triangular prism is one of the most commonly used dispersive prisms , particularly in spectroscopy and optical instruments. It is called a dispersive prism because it separates light into its different colors (spectrum) due to the different refractive indices of the glass for different wavelengths.

Explanation
Binoculars typically use Porro prisms , which are a type of reflecting prism that uses total internal reflection to redirect light. Porro prisms are named after their inventor, Ignazio Porro, and are widely used in binoculars and other optical instruments.

Explanation
Binoculars use a combination of lenses and prisms to magnify and redirect light, relying on total internal reflection to ensure minimal light loss and a bright, clear image.

Explanation
Reflecting prisms work on the principle of total internal reflection , where light is completely reflected back into the prism material rather than passing through the interface.

Explanation
Total internal reflection occurs when light travels from a denser medium (like water) to a rarer medium (like air) and the angle of incidence is greater than the critical angle.

Explanation
Thermal energy can be transferred through all three methods: Conduction : Direct transfer between particles in physical contact. Convection : Transfer through the movement of fluids. Radiation : Transfer through electromagnetic waves (e.g., light, radio waves).

Explanation
Refrigerators work on the principle of heat transfer through conduction, convection, and radiation. They use a combination of these methods to transfer heat from the inside to the outside, keeping your food and drinks cool and fresh.
