Here is a sample article from Science Cheat Sheet Class 10 on the topic of light and sound:

Light and Sound

Light and sound are both forms of energy that travel through waves. Light waves are electromagnetic waves, while sound waves are mechanical waves.

Light

Light travels in a straight line at a speed of 300,000 kilometers per second. When light hits an object, it can be reflected, refracted, or absorbed.

Reflection is the bouncing back of light from a surface. Refraction is the bending of light as it travels from one medium to another. Absorption is the conversion of light energy into another form of energy, such as heat.

Sound

Sound travels through air as a series of compressions and rarefactions. Compressions are areas of high pressure, while rarefactions are areas of low pressure.

The speed of sound in air is about 343 meters per second. Sound can be transmitted through other materials, such as solids and liquids, but it travels more slowly through these materials.

Practice Questions

  1. What are the three main types of light waves?
  2. What is the difference between reflection and refraction?
  3. What is the speed of sound in air?
  4. What are the two main types of sound waves?

Answers

  1. The three main types of light waves are radio waves, microwaves, and infrared waves, visible light, ultraviolet waves, X-rays, and gamma rays.
  2. Reflection is the bouncing back of light from a surface, while refraction is the bending of light as it travels from one medium to another.
  3. The speed of sound in air is about 343 meters per second.
  4. The two main types of sound waves are longitudinal waves and transverse waves.

Here is a Science Cheat Sheet for Class 10:

Physics

  • Motion: Newton’s three laws of motion, force, acceleration, friction, gravity, work, energy, power, momentum, circular motion, waves, sound, light, electricity, magnetism, and modern physics.
  • Newton’s laws of motion:
    • An object at rest will remain at rest unless acted upon by an external force.
    • An object in motion will remain in motion at a constant speed and in a straight line unless acted upon by an external force.
    • For every action, there is an equal and opposite reaction.
  • Force: A push or pull that can change the motion of an object.
  • Acceleration: The rate of change of velocity.
  • Friction: A force that opposes the motion of two surfaces in contact.
  • Gravity: A force that attracts any two objects with mass.
  • Work: The transfer of energy from one object to another.
  • Energy: The ability to do work.
  • Power: The rate of doing work.
  • Momentum: The mass of an object multiplied by its velocity.
  • Circular motion: Motion in a circle or part of a circle.
  • Waves: A disturbance that travels through space or time, transferring energy from one place to another.
  • Sound: A type of wave that travels through air or other media and can be heard by humans.
  • Light: A type of wave that travels through space and can be seen by humans.
  • Electricity: The flow of electrons through a conductor.
  • Magnetism: A force that attracts or repels certain materials.
  • Modern physics: The study of physics at the atomic and subatomic level.

Chemistry

  • The atom: The basic building block of matter.
  • The periodic table: An arrangement of elements in rows and columns based on their atomic number and properties.
  • Chemical bonds: Forces that hold atoms together.
  • Chemical reactions: Processes in which one or more substances are changed into one or more new substances.
  • Acids and bases: Substances that have specific properties in water.
  • Organic chemistry: The study of carbon-based compounds.

Biology

  • The cell: The basic unit of life.
  • Cell structure and function: The different parts of a cell and what they do.
  • DNA and RNA: The molecules that contain genetic information.
  • Protein synthesis: The process by which cells make proteins.
  • Metabolism: The process by which cells break down and build up molecules.
  • Cellular respiration: The process by which cells produce energy.
  • Photosynthesis: The process by which plants use sunlight to make food.
  • Genetics: The study of genes and heredity.
  • Evolution: The process by which populations of living organisms change over generations.

This is just a brief overview of the topics covered in science class 10. For more information, please consult your textbook or other resources.
