2) To provide light in a room
3) To measure temperature
4) To play music

Answer 1

A lamp is primarily used to provide light in a room. Some specialty lamps may help regulate the circadian cycle or emit infrared light for medical imaging or warmth.

Step-by-step explanation:

The primary use of a lamp is to provide light in a room. The light produced by the lamp can be either visible light, for illumination purposes, or different types of light for specific functions. For instance, some lamps are designed to emit bright light to help maintain a regular circadian cycle, especially beneficial for individuals working night shifts or those affected by seasonal changes in light. Another type of lamp, a heat lamp, radiates mostly infrared radiation, which can be sensed by the nerve endings in our skin. This is the type of light that can be used to see the underlying layer of the skin and is also useful for medical purposes, such as detecting regions of abnormally high temperature potentially indicative of disease.
