Can you use a 50mm lens for macro? 50mm lenses work best in capturing typical macro shots. However, these types of macro lenses have their drawbacks. 50mm lenses make subjects appear half “life-size” since they usually feature a 1:2 ratio, and require shooting at a much closer distance.

Why are steam burns more serious than burns caused by an equal amount of equally hot water?
Why are steam burns more serious than burns caused by an equal amount of equally hot water? Steam is more likely to cause burn injuries than boiling water because of the latent heat of vaporization. Since water expands to approximately 1,600 times its volume when it turns from liquid to steam, steam often escapes its […]

What causes the attractive forces between particles in matter?
What causes the attractive forces between particles in matter? The particles that make up some matter are close together and vibrate back and forth. If the motion of particles slows the particles move closer together. This is because the attraction between them pulls them toward each other. Strong attractive forces hold particles close together. What […]
