Force of attraction between one atom and another within a compound formed by sharing of electrons or the loss and gain of electrons this is a bond
Answer:
Explanation:
For first overtone
Standing waves will be formed lengthwise and breadth-wise in the enclosures having dimension of .75m x 1.5 m
A ) For the formation of lowest two frequencies formed by standing waves along the breadth , fundamental note and first overtone may be considered.
For fundamental note ,
the condition is
wave length λ = 2L = 2 x 0.75 m
λ = 1.5 m
frequency n = v / λ
= 343 / 1.5
= 229 Hz approx
For first overtone
λ = L = 0.75m
frequency n = v / λ
n = 343 / 0.75
= 457 Hz approx
B)
For the formation of lowest two frequencies formed by standing waves along the length , fundamental note and first overtone may be considered.
For fundamental note ,
the condition is
wave length λ = 2L = 2 x 1.5 m
λ = 3 m
frequency n = v / λ
= 343 / 3
= 114 Hz approx
frequency n = v / λ
n = 343 / 1.5
= 229 Hz approx

Answer:
A) ultraviolet light ---> violet light ----> red light-----> infrared light
Explanation:
We know that the electromagnetic spectrum with the wavelength from least to greatest is (also refer attachment)
- gamma ray
- X- rays
- Ultra-violet
- Visible
Violet
Indigo
Blue
Green
Yellow
Orange
Red
Hence the relative order of wavelengths from least to greatest in the electromagnetic spectrum is
A) ultraviolet light ---> violet light ----> red light-----> infrared light
