Answer:

It will have aim at a point "below" the insect.

From the insect's point of view, the fish will appear to be shallower than it actually is because a ray of light from the insect to the fish will be bent "towards" the normal when the ray enters the water

Light of wavelength 550nm in air is found to travel at 1.96
Sedaia [141]

Answer:

ν = 5.45 x 10¹⁴ Hz

Explanation:

given,

wavelength of light = 550 nm

                                = 550 x 10⁻⁹ m

speed of light = 1.96 x 10⁸ m/s

speed of sound = 3 x 10⁸ m/s

frequency of the light = ?

we know.

v = \nu \lambda

frequency of the light in the liquid is same as the frequency of the light in the air.

 ν is the frequency of light

\nu = \dfrac{v}{\lambda}

\nu = \dfrac{3\times 10^{8}}{550\times 10^{-9}}

    ν = 5.45 x 10¹⁴ Hz

Hence, the frequency of light in the liquid is equal to ν = 5.45 x 10¹⁴ Hz

Suppose you want to test the hypothesis that plants grow taller when they receive more sunlight. Identify and independent variab
ollegr [7]
The result that should be established is in the form
y = f(x) 
where x, the amount of sunlight is the controlled (independent) variable,
y =  height (growth) that corresponds to the amount of sunlight. Therefore y depends on x.

Clearly,
x, the amount of sunlight is the independent variable. It can be controlled.
y, the measured amount of growth is the dependent variable.

Answer:
The independent variable is the amount of sunlight.
The dependent variable is the growth.
