Concept:

Wave: It is the disturbance in which the energy is transferred from one place to another place. During the propagation of the wave, medium particles do not move. They vibrate at their position in to and fro form.

In case of the Transverse wave, medium particles vibrate perpendicular to the direction of the wave while in case of Longitudinal wave, they vibrate along the direction of the wave.

Hence, the best definition of the wave will be the disturbance that transfers the energy from one place to another place.

A car travels 300km in six hour. What is the average speed

KiRa [710]

Answer:

<h2>50 km/hr</h2>

Explanation:

The average speed of the car can be found by using the formula

$s = \frac{d}{t} \\$

d is the distance

t is the time taken

From the question we have

$s = \frac{300}{6} = 50 \\$

We have the final answer as

<h3>50 km/hr</h3>

A plane wave with a wavelength of 500 nm is incident normally ona single slit with a width of 5.0 × 10–6 m.Consider waves that r

kaheart [24]

To solve this exercise it is necessary to use the concepts related to Difference in Phase.

The Difference in phase is given by

$\Phi = \frac{2\pi \delta}{\lambda}$

Where

$\delta =$ Horizontal distance between two points

$\lambda =$ Wavelength

From our values we have,

$\lambda = 500nm = 5*10^{-6}m$

$\theta = 1\°$

The horizontal distance between this two points would be given for

$\delta = dsin\theta$

Therefore using the equation we have

$\Phi = \frac{2\pi \delta}{\lambda}$

$\Phi = \frac{2\pi(dsin\theta)}{\lambda}$

$\Phi = \frac{2\pi(5*!0^{-6}sin(1))}{500*10^{-9}}$

$\Phi= 1.096 rad \approx = 1.1 rad$

Therefore the correct answer is C.
