Question

The maximum wavelength of radiation emitted at is . What will be the maximum wavelength of radiation emitted at

• A.
• B.
• C. $1 \mu m$
• D.

Answer 1

Answer: (A)

Answer 2

$\therefore$ $\frac { \lambda _ { m _ { 2 } } } { \lambda _ { m _ { 1 } } } = \frac { T _ { 1 } } { T _ { 2 } }$ $\Rightarrow \lambda _ { m _ { 2 } } = \frac { 2000 } { 2400 } \times 4 = 3.33 \mu \mathrm { m }$
