what is IS-LM?
LM is a manufacturer's code--all LM chips were made by National Semiconductor. Similarly, SN chips were made by Texas Instruments.

New LM was created in 1976.
LM stands for "Linear Monolithic"
Linear mode
To find the illuminance at a certain distance from a light source, you can use the formula: illuminance = luminous flux / (4 * π * distance^2). Plugging in the values gives: illuminance = 1275 lm / (4 * π * (5 m)^2) ≈ 6.43 lux.
LM stands for Linear Monolithic, indicating that the LM-35 temperature sensor is a linear integrated circuit used for temperature sensing applications.
