In the grating equation nλ=dsin θ, the quantity θwill be determined in the lab
A. using a protractor.
B. using the built in angular scale on the apparatus.
C. using meter sticks and geometry/trigonometry.
STATUS
Question 6 of 7
PointsAccepted characters: numbers, decimal point markers (period or comma), sign indicators (-), spaces (e.g., as thousands separator, 5 000), “E” or “e” (used in scientific notation).
NOTE: For scientific notation, a period MUST be used as the decimal point marker. Complex numbers should be in the form (a + bi) where “a” and “b” need to have explicitly stated values. For example: {1+1i} is valid whereas {1+i} is not. {0+9i} is valid whereas {9i} is not. Use equation 1 and the values of c and h to calculate the energy (in J) of a 676 nm photon.
