Chapter 24: Q15PE (page 888)

^{Determine the amount of time it takes for X-rays of frequency $3 \times 10^{18} Hz$}^{to travel (a) 1 mm and (b) 1 cm}

Short Answer

Expert verified

The time taken for 1mm is $3.34 \times 10^{- 12} s$ .

b. The time taken for 1cm is $3.34 \times 10^{- 11} s$ .

Step by step solution

Definition of frequency

The number of waves that travel through a particular point in a given amount of time is referred to as frequency.

Given information and Formula to be used

$f = 3 \times 10^{18} Hz c = 3 \times 10^{18} m / s d = 1 mm (\frac{10^{- 3} m}{1 mm}) = 10^{- 3} m d = 1 cm (\frac{10^{- 2} m}{1 cm}) = 10^{- 2} m$

Distance is $d = ct$ ……………(1)

Calculate the amount of time it takes for X-rays of frequency 3×1018 Hz travel 1mm ?

Substitute the given data in equation (1), and we get,

$10^{- 3} m = (3 \times 10^{8} m / s) \times t t = \frac{10^{- 3} m}{3 \times 10^{8} m / s} t = 3.34 \times 10^{- 12} s$

Therefore, the time taken is $3.34 \times 10^{- 12} s$ .

Calculate the amount of time it takes for X-rays of frequency 3×1018 Hz travel 1 cm ?

Substitute the given data in equation (1), and we get,

$10^{- 2} m = (3 \times 10^{8} m / s) \times t t = \frac{10^{- 2} m}{3 \times 10^{8} m / s} t = 3.34 \times 10^{- 11} s$

Therefore, the time taken is $3.34 \times 10^{- 11} s$ .
