C++

(C) Write a C program to compute the wavelength for a frequency (integer) value you choose. Display the result using printf command. You should define the velocity of light c=3*1010 cm/sec using preprocessor directives (ie. define). wavelength = c/frequency (D) Write a C program that has integer identifiers l, and 12 (wavelengths), a constant identifier at (value, 3.14), three double variables y ,y2 and y and a constant c (value 3* 10 m/s). Assign 380 nm and 600 nm to l and 12 respectively. (1 nm = 10-meter) Compute the following at time 10-14 seconds. Y1 = 3sin ((2 * 7 * ) *time) Y2 = 5sin(( y=y+y2 Display yl and y2 and computed value of y in different lines. Be sure to include enough text to describe content of each line in the output. You will need to include the math library
