Step-by-step explanation:

Speed = wavelength × frequency

3×10⁸ m/s = (400×10⁻⁹ m) f

f = 7.5×10¹⁴

Hi there! Hopefully this helps!

--------------------------------------------------------------------------------------------------             <em>The </em><u><em>frequency is ~7.5*1014 Hz</em></u>

<em>Since visible light has a wavelength spectrum of ~</em><em><u>400 nm to ~700 nm</u></em><em>,</em><u><em> Violet light</em></u><em> has a </em><u><em>wavelength of </em></u><em>~400 nm and a </em><u><em>frequency of ~7.5*1014 Hz</em></u><em>.</em>

Answer: less than.

Explanation:

1) The function f(x)= [x] returns the integer number that is less than x.

2) For example,

[3.0] = 3

[3.01] = 3

[3.25] = 3

[3.55] = 3

[3.99] = 3

[4.00] = 4

Find four consecutive whole numbers whose sum is 74​
Rina8888 [55]

Answer:

17, 18, 19, 20

Explanation:

Let the numbers be x, x + 1, x + 2, x + 3

Their sum is equals to 74

x + x + 1 + x + 2 + x + 3 = 74     (group the variables)

x + x + x + x + 1 + 2 + 3 = 74    (simplify)

4(x) + 6 = 74                             (subtract both sides by 6)

4x = 68                                     (divide both sides by 4)

x = 17

Other numbers:

x + 1 = 17 + 1 = 18

x + 2 = 17 + 2 = 19

x + 3 = 17 + 3 = 20
