Calculate the frequency of visible light having a wavelength of 464.1 nm A 139.15
C 1.548 x 10-¹⁵
B 7.548 x 10¹⁵
D 6.460 x 10¹⁴​

Step-by-step explanation:

frequency = speed of light / wavelength

= 3.00 x 10^8 / 464.1

= 6.460 x 10^14

= D

answer: plz give a pic and answer choices so i can answer!

step-by-step explanation:

b. 1.25 hr

step-by-step explanation:

if you have a constant speed of 60 mph, then you have a ratio between 60 mi. to 1 hr. dividing both sides by 60 we get the ratio

1 mi. to

then mult. both sides by 75 we get the ratio

75 mi. to

simplifying we get

75 mi. to

or 1.25 hr.
