As it travels through a crystal, a light wave is described by the function E(x,t)=Acos[(1.57×107)x−(2.93×1015)t]. In this expres

Drupady [299]

Answer:

Speed, $v=1.86\times 10^8\ m/s$

Explanation:

It is given that,

A light wave is described by the following function as :

$E(x,t)=A\ cos[(1.57\times 10^7)x-(2.93\times 10^{15})t]$ .....(1)

The general equation of wave is given by :

$E=Acos(kx-\omega t)$ ........(2)

On comparing equation (1) and (2)

$k=(1.57\times 10^7)$

$\dfrac{2\pi}{\lambda}=(1.57\times 10^7)$

$\lambda=\dfrac{2\pi}{(1.57\times 10^7)}$

Wavelength, $\lambda=4.002\times 10^{-7}\ m$

$\omega=(2.93\times 10^{15})$

$\dfrac{2\pi}{T}=(2.93\times 10^{15})$

$\dfrac{1}{T}=\dfrac{(2.93\times 10^{15})}{2\pi}$

Frequency, $f=4.66\times 10^{14}\ Hz$

Let v is the speed of the light wave. It is given by :

$v=f\times \lambda$

$v=4.66\times 10^{14}\ Hz\times 4.002\times 10^{-7}\ m$

$v=1.86\times 10^8\ m/s$

So, the speed of the light wave is $1.86\times 10^8\ m/s$ . Hence, this is the required solution.

a 4kg block is attatched to a vertical sspring constant 800n/m. the spring stretches 5cm down. how much elastic potential energy

kow [346]

The Potential energy stored in the system is 1 J

<u>Explanation:</u>

Given-

Mass, m = 4 kg

Spring constant, k = 800 N/m

Distance, x = 5cm = 0.05m

Potential energy, U = ?

We know,

Change in potential energy is equal to the work done.

So,

$U = \frac{1}{2} k (x)^2\\\\$

By plugging in the values we get,

$U = \frac{1}{2} * 800 * (0.05)^2\\ \\U = 400 * 0.0025\\\\U = 1J\\$

Therefore, Potential energy stored in the system is 1 J

Infrared radiation from young stars can pass through the heavy dust clouds surrounding them, allowing astronomers here on Earth

Semmy [17]

Answer:

$\lambda=6.83\times 10^{-5}\ m$

Explanation:

Given that,

An infrared telescope is tuned to detect infrared radiation with a frequency of 4.39 THz.

We know that,

1 THz = 10¹² Hz

So,

f = 4.39 × 10¹² Hz

We need to find the wavelength of the infrared radiation.

We know that,

$\lambda=\dfrac{c}{f}\\\\\lambda=\dfrac{3\times 10^8}{4.39\times 10^{12}}\\\\=6.83\times 10^{-5}\ m$

So, the wavelength of the infrared radiation is $6.83\times 10^{-5}\ m$ .
