frequency's unit is Hz which mean cycles per second
given frequency * wavelength = speed of wave
speed of light = 3x10^8 m/s
wavelength = 680nm = 680x10^-9 m
frequency * 680x10^-9 m = 3x10^8 m/s
frequency = 3x10^8 / 680x10^-9
= 4.41x10^14 Hz
= 441x10^12 Hz
= 441 THz
which is the frequency for red light
Bob is just a human like us and feels stuff, its probaly due to his environment and pressures/stress but heck who really knows. Bob is Bob. and that is that.
Answer: How Autosum Excel works. Step 1: place the cursor below the column of numbers you want to sum (or to the left of the row of numbers you want to sum). Step 2: hold down the Alt key and then press the equals = sign while still holding Alt. Step 3: press Enter.
Explanation:To sum a column of numbers, select the cell immediately below the last number in the column. ...
AutoSum is in two locations: Home > AutoSum, and Formulas > AutoSum.
Once you create a formula, you can copy it to other cells instead of typing it over and over. ...
You can also use AutoSum on more than one cell at a time.
