A40-w lightbulb is 1.9 m from a screen. what is the intensity of light incident on the screen? assume that a lightbulb emits radiation uniformly in all directions (i. e., over 4π steradians). express your answer with the appropriate units.

The kinetic energy also decreases when the particles in a liquid state decrease. the liquid is solidifying so the energy is cooling down.

Aform of energy that is reflected or emitted from objects in the form of electrical and magnetic waves that can travel through space. there are many forms of  electromagnetic  energy including gamma rays, x rays, ultraviolet radiation, visible light, infrared radiation, microwaves and radio waves.
