Answer:

k = 4

Step-by-step explanation:

The graph represents y and x in direct proportion with equation

y = kx ← k is the constant of proportionality

To find k use the point (1, 4), that is x = 1, y = 4

k = \frac{y}{x} = \frac{4}{1} = 4

The inverse variation equation shows the relationship between wavelength in meters, x, and frequency, y.
wolverine [178]

Answer:

\lambda=10^{-10}\ m

Step-by-step explanation:

Given that,

The frequency of x-rays, f=3\times 10^{18}\ Hz

We need to find the wavelength for x-rays. The relation between wavelength, frequency and speed of light is given by :

v=f\lambda\\\\\lambda=\dfrac{c}{f}\\\\\lambda=\dfrac{3\times 10^{8}}{3\times 10^{18}}\\\\=10^{-10}\ m

So, the wavelength for x-rays is 10^{-10}\ m.
