MCQs

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.
