What is wavelength?
The wavelength, or the distance over which the shape of a periodic wave repeats, is the spatial period in physics. It is a property of both traveling waves and standing waves, as well as other spatial wave patterns. It is the distance between two successive corresponding locations of the same phase on the wave, such as two neighboring crests, troughs, or zero crossings. The Greek letter lambda is frequently used to denote wavelength. The term wavelength is also sometimes used to describe modulated waves, their sinusoidal envelopes, or waves created by the interference of several sinusoids.
The relationship between wavelength and frequency is inverse, assuming a sinusoidal wave flowing at a constant speed.

T<span>he relationship between wavelength and frequency is inverse.
This is as the wavelength increases the frequency decreases and as the wavelength decreases the frequency increases.
The light meets this equation that reflects the relationship between wavelength and frequency:
c = wavelength * frequency => wavelength = c / frequency
where c is the constant speed of light.

Answer:
spring constant of the spring is 1820.44 N/m
Explanation:
given data
ball mass = 4 kg
speed = 16 m/s
distance = 0.75 m
to find out
spring constant of the spring
solution
we know that kinetic energy of ball = energy store in spring as compression
so we can express it as
0.5 × m × v² = 0.5 × k × x² ....................1
so put here value we get spring constant k
m × v² = k × x²
4 × 16² = k × 0.75²
solve it we get
k = 1820.44 N/m
so spring constant of the spring is 1820.44 N/m
Answer:
magnitude of displacement of a sound pressure wave
Explanation:
The time spent in a complete cycle is called the period (T) measured in seconds and the number of cycles per second is called the frequency (f) and is measured in cycles per second or Hetz. The frequency is inverse to the period f = 1 / T. On the other hand, each segment of the rope has a certain<u> amplitude </u>(A). The amplitude is defined as the maximum displacement from the equilibrium position. The frequency is determined by the source, so that if the rope is agitated quickly, the frequency will be higher (high frequency) than if I stir it slowly (low frequency) than if I stir it slowly (low frequency) The amplitude is also determined by the source, so that if the end of the rope rises a lot from the horizontal or equilibrium position the amplitude will be large and vice versa.
