Answer:
Finally current will be
i = 0.35 A
Explanation:
As we know that power of the bulb is given by the formula
now we have
R = 240 ohm
so we have
now the current in the bulb is given as
now when length of the filament is double
so the resistance of the wire also gets double
so we have
now the current in the bulb is given as
Answer: Go ask your teacher and im sure if you search it on good it will answer faster than this.
Explanation: Have a great day \ and be safe
The ranges of frequency are:
UVA:
UVB:
Explanation:
The relationship between frequency and wavelength for an electromagnetic wave is the following:
where
f is the frequency
is the speed of light
is the wavelength
For the UVA, the range of wavelength is 320 nm - 400 nm, so
So the corresponding frequencies are
For the UVB, the range of wavelength is 280 nm - 320 nm, so
So the corresponding frequencies are
So the ranges of frequency are:
UVA:
UVB:
