A rotation motion is a motion that takes place around a fixed axis.
Like gears turning on each other.
Answer:
The frequency of the tuning is 1.065 kHz
Explanation:
Given that,
Length of tube = 40 cm
We need to calculate the difference between each of the lengths
Using formula for length



For an open-open tube,
We need to calculate the fundamental wavelength
Using formula of wavelength

Put the value into the formula


We need to calculate the frequency of the tuning
Using formula of frequency

Put the value into the formula



Hence, The frequency of the tuning is 1.065 kHz
D- All wave lengths refract at the same angle
Explanation- The amount of refraction increases as the wavelength of light decreases. Shorter wavelengths of light are slowed more and consequently experience more bending than the longer wavelengths.
Answer:
The ones that are after the light that went out are also out.
