<u>Answer:</u> The wavelength for X-rays with the given frequency is 
<u>Step-by-step explanation:</u>
To calculate the wavelength of light, we use the equation:
where,
= wavelength of the light
c = speed of light = 
= frequency of light = 
Putting the values in above equation, we get:
Hence, the wavelength for X-rays with the given frequency is
Answer:
1.C

Step-by-step explanation:
11.) our question issss.....
7 x __ = 420
all we have to do here is the opposite. so lets divide 420 by 7 here the math
420/7 = 60
sooooo answer is 60
12.) our question issss....
50 x __ = 0
well always keep in mind anything we multiply by 0 is going to be zero
so for example if we did 4 x 0 is would equal 0 because there arent even any rows to begin with
so your answer issss 0!
have a good one :)
merry christmas:D
