Key Points

• Candela (cd) is the SI unit of luminous intensity.
• Luminous intensity refers to the amount of light emitted by a source in a particular direction.
• The candela is one of the seven base units in the International System of Units (SI).
• Candela is based on the light emitted by a source that emits monochromatic radiation at a frequency of 540 × 10¹² Hz.

Additional Information

• Depth: Depth is a measure of how deep something is, such as the depth of a body of water, a hole, or a container. It is typically measured in meters or feet.
• Speed: Speed refers to the rate at which an object moves. It is the distance covered per unit of time, commonly measured in meters per second (m/s) or kilometers per hour (km/h).
• Temperature: Temperature is a measure of the average kinetic energy of the particles in a substance. It is commonly measured in degrees Celsius (°C), Fahrenheit (°F), or Kelvin (K).
