Answer:

1) The medium b has higher optical density.

2) If the optical densities of both A and B are same.

Explanation:

The refractive index of a material determines the number of times the velocity of light in that material is slower than the velocity of light in a vacuum.
The higher refractive index means slower propagation of the light in that medium.
The refractive index of the medium determines the optical density of the medium.
If the material has a higher refractive index, then its optical density is high.
If the material has a low refractive index, then its optical density is low.
The light bends towards the normal while refracting through the medium from a lower optical density medium to the higher optical density medium.
If both the mediums has the same optical density, the direction of propagation doesn't change.

Jake calculates that the frequency of a wave is 500 hertz and that the wave is moving at 1,250 m/s. What is the wavelength of th

Neko [114]

Frequency (f) = 500 hz (SI)
Velocity (V) = 1250 m/s (SI)
Wavelength (Lambda) = ? meters

$v = \lambda \times f$
$1250 = \lambda \times 500 \\ \lambda = 1250 \div 500 \\ \lambda = 2.5 \: meters$

Science If you want to find the energy quantum of light, you multiply the frequency of the radiation (v) by "h". What is "h"?

weqwewe [10]

Answer:

"h" signifies Planck's constant

Explanation:

In the equation energy E = h X v

The "h" there signifies Planck's constant

Planck's constant is a value, that shows the rate at which the energy of a photon increases/decreases, as the frequency of its electromagnetic wave changes.

It was named after Max Planck who discovered this unique relationship between the energy of a light wave and its frequency.

Planck's constant, "h" is usually expressed in Joules second

Planck's constant = $6.62607015 \times 10^{-34} J.s$
