tip 2: the speed of light, c, is constant under all circumstances.
tip 3: [tex]\lambda = \frac{c}{f}[/tex]

The amplitude of a wave is directly proportional to the energy it carries. This means that the higher the amplitude, the more energy the wave has. Amplitude is measured as the distance from the midpoint of the wave to its peak or trough.
Frequency is the number of wave cycles that pass a certain point in one second. It affects the wavelength and energy of a wave. Higher frequency waves have shorter wavelengths and carry more energy. Frequency is also related to the pitch of a sound wave and the color of a light wave.
In a longitudinal wave, the particles of the medium vibrate in the same direction as the wave is traveling. An example of this is a sound wave. In a transverse wave, the particles of the medium vibrate perpendicular to the direction of the wave. An example of this is a light wave.
The velocity of a wave is equal to the product of its frequency and wavelength. This means that as frequency increases, so does the velocity, while wavelength decreases. This relationship is described by the equation v = fλ, where v is velocity, f is frequency, and λ is wavelength.
When a wave encounters a boundary or barrier, it can reflect, or bounce back. The angle at which the wave reflects is equal to the angle at which it hits the surface. The type of reflection, whether it is regular or diffuse, depends on the smoothness of the surface. Smooth surfaces produce regular reflection, while rough surfaces produce diffuse reflection.
