Make sure that your calculator is in degree mode before using this version of the formula. Example 2: If a yellow light with a wavelength of 540 nm shines on a double slit with the slits cut 0.0100 mm apart, determine what angle you should look away from the central fringe to see the second order fringe? Do not forget to: Change the wavelength into meters. Change the slit separation into ...

How to Put a Scientific Calculator in Degree Mode | Techwalla
You’ve seen that your calculator can be in either radian mode or degree mode. So what are radians? Basically, radians are another unit with which to measure angles of rotation . Just as we measure temperature sometimes using the Fahrenheit scale and sometimes the Celsius scale or measure length sometimes using miles and sometimes kilometers, we have two ways to measure angles. Radians are ...
