Iwill mark brainliest if the number of crests that pass a point in a given time increases, what has decreased? question options: intensity wavelength frequency amplitude as taylor swift stood knee-deep in the ocean, she noted how high the waves came up on her compared to the day before. which property of waves was taylor observing? question options: amplitude speed frequency wavelength

For 1: The correct answer is Wavelength.

For 2: The correct answer is Amplitude.

Explanation:

Wavelength is defined as the distance between two crests or two troughs.

Frequency is defined as the number of oscillations that occur in 1 second.

Amplitude is defined as the maximum displacement from its equilibrium position. It is the vertical distance from the crest to the equilibrium position of the wave.

Intensity of the wave is basically the energy of the wave and it is proportional to the square of the amplitude of the wave.

Speed of the wave the is defined as the distance traveled by a given point on a wave.

As, the number of crests increases on a point which means that the number of oscillations increases and hence, the frequency increases.

Frequency is inversely proportional to the wavelength of the wave and therefore, increase in frequency will result in the decrease of wavelength.

Hence, the correct answer is Wavelength.

When Taylor Swift stood knee deep in the ocean, she noticed that the waves were high as compared to the previous day, which means that the vertical distance of the wave has increased from its mean position.

Hence, the correct answer is Amplitude.
