Oscillations
This type of oscillation occurs when the restoring force is directly proportional to the displacement.
What is Simple Harmonic Motion (SHM)?
This term refers to the property of a material that allows it to return to its original shape after the removal of an applied force.
What is Elasticity?
This term refers to the study of sound and its propagation through various mediums.
What is Acoustics?
This type of light is highly coherent and monochromatic, making it ideal for applications like surveying and measuring distances.
What is Laser light?
This type of natural hazard is characterized by the sudden shaking of the ground caused by the movement of tectonic plates.
What is an Earthquake?
The time taken by a particle to complete one full cycle of oscillation is known as this.
What is the Period?
The measure of a material's ability to resist deformation under stress is known as this property.
What is the Modulus of Elasticity?
The unit used to measure the intensity of sound is called this.
What is the Decibel (dB)?
The acronym LASER stands for Light Amplification by Stimulated Emission of Radiation, and this is the fundamental process that produces laser light.
What is Stimulated Emission?
This natural hazard is a result of rapid water movement from rivers, lakes, or oceans, causing widespread damage to buildings and infrastructure.
What is a Flood?
The angular displacement in simple harmonic motion is typically represented by this variable.
What is theta (θ)?
This type of deformation occurs when a material is stretched or compressed within the limits where it can return to its original shape after the load is removed.
What is Elastic Deformation?
This phenomenon occurs when sound waves bounce off surfaces, which can affect the acoustics of a room.
What is Echo?
This is the process by which a photon strikes an electron in an atom, causing it to jump to a higher energy level, and then emit light when it returns to a lower energy level.
What is Spontaneous Emission?
This type of landslide involves the rapid downward movement of saturated soil, often following heavy rainfall.
What is a Mudslide or Debris Flow?
In SHM, this is the maximum displacement from the equilibrium position.
What is the Amplitude?
This theory assumes that the stress and strain are proportional within the elastic limit of a material.
What is Hooke's Law?
This type of material is often used in construction to control sound and reduce echo in large halls or theaters.
What is Acoustic Insulation or Soundproofing Material?
This is the process in which photons produced in a laser are reflected between two mirrors, increasing their intensity.
What is Optical Cavity or Resonator?
This type of hazard, often occurring after heavy rainfall, involves the rapid downhill movement of loose soil and rock materials.
What is a Landslide?
This is the energy type that remains constant in an ideal simple harmonic oscillator, assuming no damping.
What is the Total Mechanical Energy (E)?
The ratio of normal stress to the corresponding strain when a material is subjected to uniform compression or tension is called this modulus.
What is the Young's Modulus?
The speed of sound in air depends on this environmental factor.
What is Temperature?
The type of laser in which the gain medium is a gas, often used in surgery and welding, is known as this.
What is a Gas Laser?
The scale used to measure the magnitude of an earthquake, based on the amplitude of seismic waves, is known as this.
What is the Richter Scale?
