Aluminum fluoride (AlF) is the first stable “closed shell” molecule ever prepared in a magneto-optical trap and cooled to millikelvin temperatures. The AlF molecular bond is exceptionally strong and ...

Waves in water are transverse. This means that the vibrations causing the waves are perpendicular to the direction of energy transfer. As this little boat demonstrates, you can see that the waves are ...

As waves travel, they set up patterns of disturbance. The amplitude of a wave is its maximum disturbance from rest (its undisturbed position). Key fact It is important to note that the amplitude is ...
