Explain what happens to a light wave that hits the surface of a pool.

1 answer:

5 0

A light wave that hits the surface of a pool gets refracted and gives us an apparent image of the surface of the pool, following the concepts of refraction.

<u>Explanation:</u>

Let’s recall the concept of refraction when a light wave passes from medium of rarer to denser. There is a change in the speed of light while travelling from medium of rarer to denser.

There can be a change in the direction as well. This property is known as “Refraction” and the best example to see refraction is watching the surface of a clean pond, lake or pool.

When the light travels from a rarer medium (air) to a denser medium (water), it changes its angle of direction and gets refracted and hit to our eye lenses. With this, we see the surface of the pool at a changed angle and it seems to be a bit shallow than its original depth.

How do i calculate acceleration? pls help! thanks :)

LenKa [72]

The acceleration is 2 mph/min

Explanation:

The acceleration of an object is the rate of change of velocity. It is defined as follows:

$a=\frac{v-u}{t}$

where

v is the final velocity

u is the initial velocity

t is the time taken for the velocity to change from u to v

For the car in this problem, we have (taking North as positive direction):

u = 25 mph

v = 35 mph

t = 5 min

Substituting into the equation, we find the acceleration:

$a=\frac{35 mph-25mph}{5min}=2 mph/min$

What Type of relationship exists between the Temperature of a Star and the Wavelength of a Star?

Debora [2.8K]

This is known as Wien's Law:
The relationship is:
wavelength = 0.0029/temperature

It is an inversely proportional relationship.

Larger animals have sturdier bones than smaller animals. A mouse's skeleton is only a few percent of its body weight, compared t

Rama09 [41]

Answer:

$a_s=4.8\times 10^{-2}~m^2$

Explanation:

Given:

cross sectional area of the bone, $a=4.8 \times 10^{-4} ~m^2$

factor of up-scaling the dimensions, $s=10$

Since we need to find the upscaled area having two degrees of the dimension therefore the scaling factor gets squared for the area being it in 2-dimensions.

The scaled up area is:

$a_s=a\times s^2$

$a_s=[4.8 \times 10^{-4}]\times 10^2$

$a_s=4.8\times 10^{-2}~m^2$

= [(10-3)/12 km] / [(49.5-32.0)/60 hour]

= 5*7 / 17.5

= 2 km/h .
