Answer:
5.3 x 10⁻⁷ m
Explanation:
Data Given
frequency = 5.7 x 10¹⁴ Hz.
Convert Hz to per seconds (s⁻¹)
1 Hz = 1 s⁻¹
5.7 x 10¹⁴ Hz = 1 x 5.7 x 10¹⁴ = 5.7 x 10¹⁴ s⁻¹
wavelength =?
Solution:
Formula used to calculate wavelength
f = c/λ
rearrange the above equation
λ = c/f ........(1)
Where:
c = speed of light = 3 x 10⁸ ms⁻¹
λ= wavelength
put the values in above equation 1
λ = 3 x 10⁸ ms⁻¹ / 5.7 x 10¹⁴ s⁻¹
λ = 5.3 x 10⁻⁷ m
So the wavelength of light = 5.3 x 10⁻⁷ m
Answer:
Aluminum is ideal for aircraft manufacture because it's lightweight and strong. Aluminum is roughly a third the weight of steel, allowing an aircraft to carry more weight and or become more fuel efficient. Furthermore, aluminum's high resistance to corrosion ensures the safety of the aircraft and its passengers.
Explanation:
For example
Na2CO3
[na=23 o=16c=12]
2x23+12
+16x3
46+12+48
106
%comp of Na=46/110x106=44%
%comp of C =12/110x106=12%
% comp o O=48/110x106= 46%
