Explanation:
The refraction is the change in the direction of light while travelling from the one medium to another due to having different speeds in different mediums.
To determine how much light gets refracted, it depends on the density of substance and the wavelength and the angle at which light enters the substance.
Light travels more slowly in denser medium than the rarer medium. The refractive index of glass is more than water or air. Light gets refracted more in this. When the light travels from rarer to denser then the light will get bend towards the normal. When the light travels from denser to rarer then the light will get bend away from the normal.
Glass is more denser than air or water. Water is more denser than the air. When light travels from air to glass then the light gets bends towards the normal. When the light travels from glass to the air then light gets bends away from the normal.
Therefore, the light gets refracted more in the glass than air to water.
Answer: the thing that brings you life- h2o- idrk the question but if this helps your welcome ^-^have a good day
Explanation:
Answer:
1) λ = 24.7 cm, 2) f = 13.88 Hz, 3) L = 117.3 cm
Explanation:
1) This is a resonance process, that is, the wave going downwards will interfere with the wave going upwards.
This is a tube with one end closed and the other open, at the closed end there is a node and at the open end a belly, so the resonances are
L = λ / 4
λ = 4L 1st harmonic
λ = 4L / 3 third harmonic
λ = 4L / 5 fifth harmonic
λ = 4L / n ’ n’ odd number n ’= (2n +1)
the wavelength is requested for the eighth resonance n = 8, the corresponding prime number is
n ’= 2 8 +1
n ’= 17
we substitute
λ = 4 105/17
λ = 24.7 cm
2) the speed of the wave is related to the wavelength and frequency
v = λf
f = v /λ
f = 343 / 24.7
f = 13.88 Hz
3) the next resonance occurs for n = 9, so the prime number is
n ’= 2 9 +1
n ’= 19
L = n’ λ / 4
L = 19 λ / 4
We must suppose a value for the wavelength, if the wavelength is present in the tube and the length of the column increases, the resonance number increases
L = 19 24.7/4
L = 117.3 cm
The best and most correct answer among the choices provided by your question is the third choice or letter C.
<span>The speed of sound in steel is greater than it is in air because steel is more dense than air.</span>

Gravity is affected by the size of an object and the distance between the objects. When the mass of an object increases the force of gravity increases as well.
