Explanation :

Given that,

The speed of all electromagnetic waves is, v=3\times 10^8\ m/s

Frequency of x-ray,\nu=1.18\times 10^{18}\ Hz

The speed of the wave is defined as the product of the frequency and the wavelength.

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

\lambda=\dfrac{3\times 10^8}{1.18\times 10^{18}}

\lambda=2.54\times 10^{-10}\ m

So, the correct option is (c).

Hence, this is the required solution.

Taya2010 [7]
We are given with the expression d = ut + 0.5 at^2 and is asked to express the equation in terms of a. First, we transpose ut to the left side, then we multiply to the equation and divide lastly the resulting equation by t^2. The final expression becomes a = 2(d-ut)/t^2.

Doubling the frequency of a wave source doubles the speed of the wave assuing that wavelength remains the same? True or false? W
SVETLANKA909090 [29]

Answer:true,because velocity is directly proportional to speed or velocity

Explanation:

Velocity = frequency x wavelength

The velocity or speed varies directly with the frequency, so as the frequency is increased, the velocity or speed is also increased
