Question
A wave vibrates up and down 16 times a second and travels a distance 4m in one second. Find the wavelength of wave?
Solution
Distance travelled by the wave in 1 sec = 4 m
Therefore,
Therefore,
Velocity of wave = 4m/s.
Also the wave vibrates up and down 16 times a second, therefore the frequency of wave is 16Hz.
Now using the formula,
∴![<pre>uncaught exception: <b>mkdir(): Permission denied (errno: 2) in /home/config_admin/public/felixventures.in/public/application/css/plugins/tiny_mce_wiris/integration/lib/com/wiris/util/sys/Store.class.php at line #56mkdir(): Permission denied</b><br /><br />in file: /home/config_admin/public/felixventures.in/public/application/css/plugins/tiny_mce_wiris/integration/lib/com/wiris/util/sys/Store.class.php line 56<br />#0 [internal function]: _hx_error_handler(2, 'mkdir(): Permis...', '/home/config_ad...', 56, Array)
