Alight wave travels at a speed of 3.0 * 108 meters/second. if the wavelength is 7.0 x 10-7 meters, what is the freq
2.5 x 10-14 hertz
b. 4.3 * 1014 hertz
c.
1.7 * 10-14 hertz
d.
5.1 x 10-14 hertz

B = Frequency =  4.3  × 10¹⁴Hz

Explanation:

Given data:

Speed of light = 3 × 10⁸ ms⁻¹

Wavelength of light = 7.0 × 10⁻⁷ m.

Frequency = ?

Solution:

Formula:

Speed of light = wavelength × frequency

Frequency = Speed of light /wavelength

Frequency = 3 × 10⁸ ms⁻¹ /7.0 × 10⁻⁷ m.

Frequency = 0.43  × 10⁸⁺⁷ s⁻¹

Frequency =  0.43  × 10¹⁵s⁻¹

s⁻¹ = Hz

Frequency = 4.3  × 10¹⁴Hz

answer

i think the answer is a) as air pressure in an area increases, the density of the gas particles in that area decreases.

hope it

practical process described pest part of scientific investigation.

because practical knowledge is powerful then therotical knowledge.
