What is the distance from the rest position in a wave to the crest or trough?
Let us look at a cosine wave, described by y = A cos (b). When b = 0 degrees, y = A (<-- peak) When b = 90 degrees, y = 0 (<-- rest position of the wave) When b = 180 degrees, y = -A (<-- trough) When b = 270 degrees, y=0 (<-- rest position again) and so on. If we force A to be a function of time, then the wave becomes a standing wave (see the related link). The peak and trough will reverse their relative position for every half of a period. Regardless, the trough at any time and the rest position is still 90 degrees, or one quarter of a wavelength. ====================================
Wave A has an amplitude of 3 and wave B has an amplitude of 3 What will happen when the trough of wave A meets the trough of wave B?
Constructive interference which theoretically would result in a 6 amplitude as long as the frequency and wavelength of the 2 waves are the same.
Why electromagnetism is a wave are using a slinky?
b
Which wave has a greater frequency- wave a where a crest is seen once every second or wave b where a crest is seen some evry minute?
The wave that has a crest every second has a greater frequency.
What is the angle of incidence equivalent to?
Snell's law equates the ratios of two angles and wave velocity.sin(a)/V1 = sin(b)/V2When a wave strikes a medium some energy is reflected and some passes through.a is the angle between the longitudinal wave velocity of the wave in the first medium as measured from a perpendicular to the tangent of the surface of the medium.b is the angle between that perpendicular and the longitudinal wave as it is refracted within the medium.The angle of incidence refers to these angles.Clearly, if the wave strikes perpendicular to the surface, a = b = 0 and sin(a) = sin(b) = 1
What are sound waves A Standing wave B Transverse wave C Longitudinal wave?
Longitudinal (also called compression) wave
How does the expression for the velocity of the longitudinal wave differ from transverse wave?
The waves are the scalar and vector parts of Quaternion derivatives: [d/dr, DEL]2 [b,B] = The Longitudinal wave (d2/dr2 - DEL2)b - 2d/dr DEL.B is a scalar wave The Transverse wave (d2/dr2 - DEL2)B + 2d/dr( DEL b + DELxB) is a vector wave.
What energy profile best shows that the formation of NO2 requires 33.1 kJmol?
Brainly says it’s energy profile B for APEX please correct if i’m wrong.

Which p waves takes a more direct route to the receiving station wave a or wave b?
wave a

B. wave lines approaching shore at an angle.
What form does a wave front have A sine wave B surface of a sphere?
A wave front has a form that is a surface of a sphere.
Wave A has an amplitude of 3 and wave B has an amplitude of 3 What will happen when the trough of wave A meets the trough of wave B?
Constructive interference which theoretically would result in a 6 amplitude as long as the frequency and wavelength of the 2 waves are the same.
